FLINT has been developed since 2007 by a large number of people. Initially
|
||||
the library was started by David Harvey and William Hart. Later maintenance
|
||||
of the library was taken over solely by William Hart.
|
||||
|
||||
The authors of FLINT to date:
|
||||
|
||||
$\bullet$ William Hart -- integer and polynomial arithmetic, factorisation and
|
||||
primality testing, general infrastructure (supported by EPSRC Grant
|
||||
EP/G004870/1 and DFG Priority programme SPP1489)
|
||||
|
||||
$\bullet$ Sebastian Pancratz -- polynomial arithmetic over $\Z$, $\Z/n\Z$ and
|
||||
$\Q$, $p$-adic and $q$-adic arithmetic, including polynomials and matrices

$\bullet$ In addition Michael Abshoff, William Stein and Robert Bradshaw have
|
||||
contributed to the build system of FLINT.
|
||||
|
||||
$\bullet$ Michael Abshoff deserves special recognition for his help in
|
||||
resolving a number of difficult build issues which came to light as FLINT was
|
||||
incorporated into SAGE and for bringing numerous bugs to the attention of the
|
||||
FLINT maintainers. Michael regularly checked FLINT for memory leaks and
|
||||
corruption, which directly led to numerous issues being identified early!
|
||||
He also helped with setting up various pieces of infrastructure for the FLINT
|
||||
project.
|
||||
|
||||
$\bullet$ Numerous people have contributed to wrapping FLINT in Sage and
|
||||
debugging, including Mike Hansen, Jean-Pierre Flori, Burcin Erocal, Robert
|
||||
Bradshaw, Martin Albrecht, Sebastian Pancratz, Fredrik Johansson, Jeroen
|
||||
Demeyer and Leif Lionhardy, amongst others.
|
||||
|
||||
Some code (notably \code{longlong.h} and \code{clz_tab.c}) has been used from
|
||||
the GMP library, whose main author is Torbjorn Granlund.
|
||||
|
||||
FLINT 2 was a complete rewrite from scratch which began in about 2010.

Instructions on intalling flint 2
|
||||
---------------------------------
|
||||
|
||||
FLINT 2 follows a standard format for installation:
|
||||
|
||||
./configure
|
||||
make
|
||||
make check
|
||||
make install
|
||||
|
||||
However, this assumes that MPIR and MPFR are already installed on your system in
|
||||
/usr/local. If the libraries are not in this location you must specify where
|
||||
they are by passing their location to configure. It also assumes you wish to
|
||||
install FLINT 2 at the prefix /usr/local. If not you must pass the prefix (the
|
||||
directory containing lib and include subdirectories into which FLINT will be
|
||||
installed) to configure:
|
||||
|
||||
./configure --with-mpir=/home/user1/mpir-2.1.1/ --with-mpfr=/usr --prefix=/usr
|
||||
|
||||
Note that the FLINT configure system can handle MPIR/MPFR as installed (in lib
|
||||
and include dirs) at some location, or as source builds (built from source and
|
||||
not installed).
|
||||
|
||||
For further configure and make options, please refer to the FLINT 2
|
||||
documentation.

FLINT 2
|
||||
=======
|
||||
|
||||
FLINT (Fast Library for Number Theory) is a C library in support of computations
|
||||
in number theory. It's also a research project into algorithms in number theory.
|
||||
|
||||
FLINT 2 is a complete rewrite of the FLINT library from scratch. It includes
|
||||
much cleaner code and in many cases much faster algorithms and implementations.
|
||||
|
||||
At this stage FLINT consists mainly of fast integer and polynomial
|
||||
arithmetic and linear algebra. In the future it is planned that FLINT will
|
||||
contain algorithms for algebraic number theory and other number theoretic
|
||||
functionality.

Sets $s$ to $S(n,k)$ where $S(n,k)$ denotes an unsigned Stirling
|

number of the first kind $|S_1(n, k)|$, a signed Stirling number
|

of the first kind $S_1(n, k)$, or a Stirling number of the second

|

$S(n,k)$ is taken to be zero if $n < 0$ or $k < 0$.
|

These three functions are useful for computing isolated Stirling

Computes the row of Stirling numbers

To compute a full row, this function can be called with

Given the vector \code{prev} containing a row of Stirling numbers
|

\code{S(n-1,0), S(n-1,1), S(n-1,2), ..., S(n-1,klen-1)}, computes

and stores in the row argument
|

\code{S(n,0), S(n,1), S(n,2), ..., S(n,klen-1)}.
|

|

If \code{klen} is greater than \code{n}, the output ends with

\code{S(n,n) = 1} followed by \code{S(n,n+1) = S(n,n+2) = ... = 0}.

In this case, the input only needs to have length \code{n-1};

only the input entries up to \code{S(n-1,n-2)} are read.

void arith_bell_number(fmpz_t b, ulong n)
|
||||
|
||||
Sets $b$ to the Bell number $B_n$, defined as the
|
||||
number of partitions of a set with $n$ members. Equivalently,
|
||||
$B_n = \sum_{k=0}^n S_2(n,k)$ where $S_2(n,k)$ denotes a Stirling number
|
||||
of the second kind.
|
||||
|
||||
This function automatically selects between table lookup, binary
|
||||
splitting, and the multimodular algorithm.
|
||||
|
||||
void arith_bell_number_bsplit(fmpz_t res, ulong n)
|
||||
|
||||
Computes the Bell number $B_n$ by evaluating a precise truncation of
|
||||
the series $B_n = e^{-1} \sum_{k=0}^{\infty} \frac{k^n}{k!}$ using
|
||||
binary splitting.
|
||||
|
||||
void arith_bell_number_multi_mod(fmpz_t res, ulong n)
|
||||
|
||||
Computes the Bell number $B_n$ using a multimodular algorithm.
|
||||
|
||||
This function evaluates the Bell number modulo several limb-size
|
||||
primes using\\ \code{arith_bell_number_nmod} and reconstructs the integer
|
||||
value using the fast Chinese remainder algorithm.
|
||||
A bound for the number of needed primes is computed using
|
||||
\code{arith_bell_number_size}.
|
||||
|
||||
void arith_bell_number_vec(fmpz * b, slong n)
|
||||
|
||||
Sets $b$ to the vector of Bell numbers $B_0, B_1, \ldots, B_{n-1}$
|
||||
inclusive. Automatically switches between the \code{recursive}
|
||||
and \code{multi_mod} algorithms depending on the size of $n$.
|
||||
|
||||
void arith_bell_number_vec_recursive(fmpz * b, slong n)
|
||||
|
||||
Sets $b$ to the vector of Bell numbers $B_0, B_1, \ldots, B_{n-1}$
|
||||
inclusive. This function uses table lookup if $B_{n-1}$ fits in a
|
||||
single word, and a standard triangular recurrence otherwise.
|
||||
|
||||
void arith_bell_number_vec_multi_mod(fmpz * b, slong n)
|
||||
|
||||
Sets $b$ to the vector of Bell numbers $B_0, B_1, \ldots, B_{n-1}$
|
||||
inclusive.
|
||||
|
||||
This function evaluates the Bell numbers modulo several limb-size
|
||||
primes using\\ \code{arith_bell_number_nmod_vec} and reconstructs the
|
||||
integer values using the fast Chinese remainder algorithm.
|
||||
A bound for the number of needed primes is computed using
|
||||
\code{arith_bell_number_size}.
|
||||
|
||||
mp_limb_t bell_number_nmod(ulong n, nmod_t mod)
|
||||
|
||||
Computes the Bell number $B_n$ modulo a prime $p$ given by \code{mod}
|
||||
|
||||
After handling special cases, we use the formula
|
||||
|
||||
$$B_n = \sum_{k=0}^n \frac{(n-k)^n}{(n-k)!}
|
||||
\sum_{j=0}^k \frac{(-1)^j}{j!}.$$
|
||||
|
||||
We arrange the operations in such a way that we only have to
|
||||
multiply (and not divide) in the main loop. As a further optimisation,
|
||||
we use sieving to reduce the number of powers that need to be
|
||||
evaluated. This results in $O(n)$ memory usage.
|
||||
|
||||
The divisions by factorials require $n > p$, so we fall back to
|
||||
calling\\ \code{bell_number_nmod_vec_recursive} and reading off the
|
||||
last entry when $p \le n$.
|
||||
|
||||
void arith_bell_number_nmod_vec(mp_ptr b, slong n, nmod_t mod)
|
||||
|
||||
Sets $b$ to the vector of Bell numbers $B_0, B_1, \ldots, B_{n-1}$
|
||||
inclusive modulo a prime $p$ given by \code{mod}. Automatically
|
||||
switches between the \code{recursive} and \code{series} algorithms
|
||||
depending on the size of $n$ and whether $p$ is large enough for the
|
||||
series algorithm to work.
|
||||
|
||||
void arith_bell_number_nmod_vec_recursive(mp_ptr b, slong n, nmod_t mod)
|
||||
|
||||
Sets $b$ to the vector of Bell numbers $B_0, B_1, \ldots, B_{n-1}$
|
||||
inclusive modulo a prime $p$ given by \code{mod}. This function uses
|
||||
table lookup if $B_{n-1}$ fits in a single word, and a standard
|
||||
triangular recurrence otherwise.
|
||||
|
||||
void arith_bell_number_nmod_vec_series(mp_ptr b, slong n, nmod_t mod)
|
||||
|
||||
Sets $b$ to the vector of Bell numbers $B_0, B_1, \ldots, B_{n-1}$
|
||||
inclusive modulo a prime $p$ given by \code{mod}. This function
|
||||
expands the exponential generating function
|
||||
$$\sum_{k=0}^{\infty} \frac{B_n}{n!} x^n = \exp(e^x-1).$$
|
||||
We require that $p \ge n$.
|
||||
|
||||
double arith_bell_number_size(ulong n)
|
||||
|
||||
Returns $b$ such that $B_n < 2^{\lfloor b \rfloor}$, using the inequality
|
||||
$$B_n < \left(\frac{0.792n}{\log(n+1)}\right)^n$$
|
||||
which is given in \cite{BerTas2010}.

void _arith_bernoulli_number(fmpz_t num, fmpz_t den, ulong n)
|

|

Sets \code{(num, den)} to the reduced numerator and denominator
|

of the $n$-th Bernoulli number. As presently implemented,
|
||||
this function simply calls\\ \code{_arith_bernoulli_number_zeta}.
|
||||
|

void arith_bernoulli_number(fmpq_t x, ulong n)
|

|

Sets \code{x} to the $n$-th Bernoulli number. This function is

equivalent to\\ \code{_arith_bernoulli_number} apart from the output
|

being a single \code{fmpq_t} variable.
|
||||
|
||||
void _arith_bernoulli_number_vec(fmpz * num, fmpz * den, slong n)
|
||||
|
||||
Sets the elements of \code{num} and \code{den} to the reduced
|
||||
numerators and denominators of the Bernoulli numbers
|
||||
$B_0, B_1, B_2, \ldots, B_{n-1}$ inclusive. This function automatically
|
||||
chooses between the \code{recursive}, \code{zeta} and \code{multi_mod}
|
||||
algorithms according to the size of $n$.
|
||||
|
||||
void arith_bernoulli_number_vec(fmpq * x, slong n)
|
||||
|
||||
Sets the \code{x} to the vector of Bernoulli numbers
|
||||
$B_0, B_1, B_2, \ldots, B_{n-1}$ inclusive. This function is
|
||||
equivalent to \code{_arith_bernoulli_number_vec} apart
|
||||
from the output being a single \code{fmpq} vector.
|
||||
|
||||
void arith_bernoulli_number_denom(fmpz_t den, ulong n)
|
||||
|
||||
Sets \code{den} to the reduced denominator of the $n$-th
|
||||
Bernoulli number $B_n$. For even $n$, the denominator is computed
|
||||
as the product of all primes $p$ for which $p - 1$ divides $n$;
|
||||
this property is a consequence of the von Staudt-Clausen theorem.
|
||||
For odd $n$, the denominator is trivial (\code{den} is set to 1 whenever
|
||||
$B_n = 0$). The initial sequence of values smaller than $2^{32}$ are
|
||||
looked up directly from a table.
|
||||
|
||||
double arith_bernoulli_number_size(ulong n)
|
||||
|
||||
Returns $b$ such that $|B_n| < 2^{\lfloor b \rfloor}$, using the inequality
|
||||
$$|B_n| < \frac{4 n!}{(2\pi)^n}$$ and $n! \le (n+1)^{n+1} e^{-n}$.
|
||||
No special treatment is given to odd $n$. Accuracy is not guaranteed
|
||||
if $n > 10^{14}$.
|
||||
|
||||
void arith_bernoulli_polynomial(fmpq_poly_t poly, ulong n)
|
||||
|
||||
Sets \code{poly} to the Bernoulli polynomial of degree $n$,
|
||||
$B_n(x) = \sum_{k=0}^n \binom{n}{k} B_k x^{n-k}$ where $B_k$
|
||||
is a Bernoulli number. This function basically calls
|
||||
\code{arith_bernoulli_number_vec} and then rescales the coefficients
|
||||
efficiently.
|
||||
|
||||
void _arith_bernoulli_number_zeta(fmpz_t num, fmpz_t den, ulong n)
|
||||
|
||||
Sets \code{(num, den)} to the reduced numerator and denominator
|
||||
of the $n$-th Bernoulli number.
|
||||
|
||||
This function first computes the exact denominator and a bound
|
||||
for the size of the numerator. It then computes an approximation
|
||||
of $|B_n| = 2n! \zeta(n) / (2 \pi)^n$ as a floating-point number
|
||||
and multiplies by the denominator to to obtain a real number
|
||||
that rounds to the exact numerator. For tiny $n$, the numerator
|
||||
is looked up from a table to avoid unnecessary overhead.
|
||||
|
||||
void _arith_bernoulli_number_vec_recursive(fmpz * num, fmpz * den, slong n)
|
||||
|
||||
Sets the elements of \code{num} and \code{den} to the reduced
|
||||
numerators and denominators of $B_0, B_1, B_2, \ldots, B_{n-1}$
|
||||
inclusive.
|
||||
|
||||
The first few entries are computed using \code{arith_bernoulli_number},
|
||||
and then Ramanujan's recursive formula expressing $B_m$ as a sum over
|
||||
$B_k$ for $k$ congruent to $m$ modulo 6 is applied repeatedly.
|
||||
|
||||
To avoid costly GCDs, the numerators are transformed internally
|
||||
to a common denominator and all operations are performed using
|
||||
integer arithmetic. This makes the algorithm fast for small $n$,
|
||||
say $n < 1000$. The common denominator is calculated directly
|
||||
as the primorial of $n + 1$.

numerators and denominators of $B_0, B_1, B_2, \ldots, B_{n-1}$

inclusive. Uses the generating function

|

$$\frac{x^2}{\cosh(x)-1} = \sum_{k=0}^{\infty}
|
||||
\frac{(2-4k) B_{2k}}{(2k)!} x^{2k}$$
|
||||
|
||||
which is evaluated modulo several limb-size primes using \code{nmod_poly}
|
||||
arithmetic to yield the numerators of the Bernoulli numbers after
|
||||
multiplication by the denominators and CRT reconstruction. This formula,
|
||||
given (incorrectly) in \citep{BuhlerCrandallSompolski1992}, saves about
|

half of the time compared to the usual generating function $x/(e^x-1)$

since the odd terms vanish.

|

We factor $n$ and use the identity $\tau(pq) = \tau(p) \tau(q)$
|
||||
along with the recursion
|

$\tau(p^{r+1}) = \tau(p) \tau(p^r) - p^{11} \tau(p^{r-1})$
|

for prime powers.
|

|

The base values $\tau(p)$ are obtained using the function

\code{arith_ramanujan_tau_series()}. Thus the speed of

\code{arith_ramanujan_tau()} depends on the largest prime factor of $n$.

Cyclotomic polynomials

|

void _arith_cyclotomic_polynomial(fmpz * a, ulong n, mp_ptr factors,
|
||||
slong num_factors, ulong phi)
|
||||
|
||||
Sets \code{a} to the lower half of the cyclotomic polynomial $\Phi_n(x)$,
|
||||
given $n \ge 3$ which must be squarefree.
|
||||
|
||||
A precomputed array containing the prime factors of $n$ must be provided,
|
||||
as well as the value of the Euler totient function $\phi(n)$ as \code{phi}.
|
||||
If $n$ is even, 2 must be the first factor in the list.
|
||||
|
||||
The degree of $\Phi_n(x)$ is exactly $\phi(n)$. Only the low
|
||||
$(\phi(n) + 1) / 2$ coefficients are written; the high coefficients
|
||||
can be obtained afterwards by copying the low coefficients
|
||||
in reverse order, since $\Phi_n(x)$ is a palindrome for $n \ne 1$.
|
||||
|
||||
We use the sparse power series algorithm described as Algorithm 4
|
||||
\cite{ArnoldMonagan2011}. The algorithm is based on the identity
|
||||
|
||||
$$\Phi_n(x) = \prod_{d|n} (x^d - 1)^{\mu(n/d)}.$$
|
||||
|
||||
Treating the polynomial as a power series, the multiplications and
|
||||
divisions can be done very cheaply using repeated additions and
|
||||
subtractions. The complexity is $O(2^k \phi(n))$ where $k$ is the
|
||||
number of prime factors in $n$.
|
||||
|
||||
To improve efficiency for small $n$, we treat the \code{fmpz}
|
||||
coefficients as machine integers when there is no risk of overflow.
|
||||
The following bounds are given in Table 6 of \cite{ArnoldMonagan2011}:
|
||||
|
||||
For $n < 10163195$, the largest coefficient in any $\Phi_n(x)$
|
||||
has 27 bits, so machine arithmetic is safe on 32 bits.
|
||||
|
||||
For $n < 169828113$, the largest coefficient in any $\Phi_n(x)$
|
||||
has 60 bits, so machine arithmetic is safe on 64 bits.
|
||||
|
||||
Further, the coefficients are always $\pm 1$ or 0 if there are
|
||||
exactly two prime factors, so in this case machine arithmetic can be
|
||||
used as well.
|
||||
|
||||
Finally, we handle two special cases: if there is exactly one prime
|
||||
factor $n = p$, then $\Phi_n(x) = 1 + x + x^2 + \ldots + x^{n-1}$,
|
||||
and if $n = 2m$, we use $\Phi_n(x) = \Phi_m(-x)$ to fall back
|
||||
to the case when $n$ is odd.
|
||||
|
||||
void arith_cyclotomic_polynomial(fmpz_poly_t poly, ulong n)
|
||||
|

Sets \code{poly} to the $n$th cyclotomic polynomial, defined as
|
||||
|
||||
$$\Phi_n(x) = \prod_{\omega} (x-\omega)$$
|
||||
|
||||
where $\omega$ runs over all the $n$th primitive roots of unity.
|
||||
|
||||
We factor $n$ into $n = qs$ where $q$ is squarefree,
|
||||
and compute $\Phi_q(x)$. Then $\Phi_n(x) = \Phi_q(x^s)$.
|
||||
|
||||
void _arith_cos_minpoly(fmpz * coeffs, slong d, ulong n)
|
||||
|

For $n \ge 1$, sets \code{(coeffs, d+1)} to the minimal polynomial
|
||||
$\Psi_n(x)$ of $\cos(2 \pi / n)$, scaled to have integer coefficients
|
||||
by multiplying by $2^d$ ($2^{d-1}$ when $n$ is a power of two).
|
||||
|
||||
The polynomial $\Psi_n(x)$ is described in \cite{WaktinsZeitlin1993}.
|
||||
As proved in that paper, the roots of $\Psi_n(x)$ for $n \ge 3$ are
|
||||
$\cos(2 \pi k / n)$ where $0 \le k < d$ and where $\gcd(k, n) = 1$.
|
||||
|
||||
To calculate $\Psi_n(x)$, we compute the roots numerically with MPFR
|
||||
and use a balanced product tree to form a polynomial with fixed-point
|
||||
coefficients, i.e. an approximation of $2^p 2^d \Psi_n(x)$.
|
||||
|
||||
To determine the precision $p$, we note that the coefficients
|
||||
in $\prod_{i=1}^d (x - \alpha)$ can be bounded by the central
|
||||
coefficient in the binomial expansion of $(x+1)^d$.
|
||||
|
||||
When $n$ is an odd prime, we use a direct formula for the coefficients
|
||||
(\url{http://mathworld.wolfram.com/TrigonometryAngles.html}).

degree $\phi(n) / 2$ otherwise.

We allow $n = 0$ and define $\Psi_0 = 1$.

Dedekind sums
|
||||
|
||||
Most of the definitions and relations used in the following section
|
||||
are given by Apostol \cite{Apostol1997}. The Dedekind sum $s(h,k)$ is
|
||||
defined for all integers $h$ and $k$ as
|
||||
|
||||
$$s(h,k) = \sum_{i=1}^{k-1} \left(\left(\frac{i}{k}\right)\right)
|
||||
\left(\left(\frac{hi}{k}\right)\right)$$
|
||||
|
||||
where
|
||||
|
||||
$$((x))=\begin{cases}
|
||||
x-\lfloor x\rfloor-1/2 &\mbox{if }
|
||||
x\in\mathbb{Q}\setminus\mathbb{Z}\\
|
||||
0 &\mbox{if }x\in\mathbb{Z}.
|
||||
\end{cases}$$
|
||||
|
||||
If $0 < h < k$ and $(h,k) = 1$, this reduces to
|
||||
|
||||
$$s(h,k) = \sum_{i=1}^{k-1} \frac{i}{k}
|
||||
\left(\frac{hi}{k}-\left\lfloor\frac{hi}{k}\right\rfloor
|
||||
-\frac{1}{2}\right).$$
|
||||
|
||||
The main formula for evaluating the series above is the following.
|
||||
Letting $r_0 = k$, $r_1 = h$, $r_2, r_3, \ldots, r_n, r_{n+1} = 1$
|
||||
be the remainder sequence in the Euclidean algorithm for
|
||||
computing GCD of $h$ and $k$,
|
||||
|
||||
$$s(h,k) = \frac{1-(-1)^n}{8} - \frac{1}{12} \sum_{i=1}^{n+1}
|
||||
(-1)^i \left(\frac{1+r_i^2+r_{i-1}^2}{r_i r_{i-1}}\right).$$
|
||||
|
||||
Writing $s(h,k) = p/q$, some useful properties employed are
|
||||
$|s| < k / 12$, $q | 6k$ and $2|p| < k^2$.

||||

void arith_dedekind_sum_naive(fmpq_t s, const fmpz_t h, const fmpz_t k)
|
||||
|
||||
Computes $s(h,k)$ for arbitrary $h$ and $k$ using a straightforward
|
||||
implementation of the defining sum using \code{fmpz} arithmetic.
|
||||
This function is slow except for very small $k$ and is mainly
|
||||
intended to be used for testing purposes.
|
||||
|
||||
double arith_dedekind_sum_coprime_d(double h, double k)
|
||||
|
||||
Returns an approximation of $s(h,k)$ computed by evaluating the
|
||||
remainder sequence sum using double-precision arithmetic.
|
||||
Assumes that $0 < h < k$ and $(h,k) = 1$, and that $h$, $k$ and
|
||||
their remainders can be represented exactly as doubles, e.g.
|
||||
$k < 2^{53}$.
|
||||
|
||||
We give a rough error analysis with IEEE double precision arithmetic,
|
||||
assuming $2 k^2 < 2^{53}$. By assumption, the terms in the sum evaluate
|
||||
exactly apart from the division. Thus each term is bounded in magnitude
|
||||
by $2k$ and its absolute error is bounded by $k 2^{-52}$.
|
||||
By worst-case analysis of the Euclidean algorithm, we also know that
|
||||
no more than 40 terms will be added.
|
||||
|
||||
It follows that the absolute error is at most $C k 2^{-53}$ for
|
||||
some constant $C$. If we multiply the output by $6 k$ in order
|
||||
to obtain an integer numerator, the order of magnitude of the error
|
||||
is around $6 C k^2 2^{-53}$, so rounding to the nearest integer gives
|
||||
a correct numerator whenever $k < 2^{26-d}$ for some small number of
|
||||
guard bits $d$. A computation has shown that $d = 5$ is sufficient,
|
||||
i.e. this function can be used for exact computation when
|
||||
$k < 2^{21} \approx 2 \times 10^6$. This bound can likely be improved.

void arith_dedekind_sum_coprime_large(fmpq_t s, const fmpz_t h, const fmpz_t k)
|

Computes $s(h,k)$ for $h$ and $k$ satisfying $0 \le h \le k$ and

$(h,k) = 1$. This function effectively evaluates the remainder
|
||||
sequence sum using \code{fmpz} arithmetic, without optimising for

||||
any special cases. To avoid rational arithmetic, we use

the integer algorithm of Knuth \cite{Knuth1977}.

Computes $s(h,k)$ for $h$ and $k$ satisfying $0 \le h \le k$
|
||||
and $(h,k) = 1$.
|
||||
|
||||
This function calls \code{arith_dedekind_sum_coprime_d} if $k$ is small
|
||||
enough for a double-precision estimate of the sum to yield a correct
|
||||
numerator upon multiplication by $6k$ and rounding to the nearest integer.
|
||||
Otherwise, it calls \code{arith_dedekind_sum_coprime_large}.
|
||||
|
||||
void arith_dedekind_sum(fmpq_t s, const fmpz_t h, const fmpz_t k)
|
||||
|
||||
Computes $s(h,k)$ for arbitrary $h$ and $k$. If the caller
|
||||
can guarantee $0 < h < k$ and $(h,k) = 1$ ahead of time, it is always
|
||||
cheaper to call \code{arith_dedekind_sum_coprime}.
|
||||
|
||||
This function uses the following identities to reduce the general
|
||||
case to the situation where $0 < h < k$ and $(h,k) = 1$:
|
||||
If $k \le 2$ or $h = 0$, $s(h,k) = 0$.
|
||||
If $h < 0$, $s(h,k) = -s(-h,k)$.
|
||||
For any $q > 0$, $s(qh,qk) = s(h,k)$.
|
||||
If $0 < k < h$ and $(h,k) = 1$,
|
||||
$s(h,k) = (1+h(h-3k)+k^2) / (12hk) - t(k,h).$

The special \code{trig_prod_t} structure \code{prod} represents a
|
||||
product of cosines of rational arguments, multiplied by an algebraic
|
||||
prefactor. It must be pre-initialised with \code{trig_prod_init}.
|
||||
|
||||
This function assumes that $24k$ and $24n$ do not overflow a single limb.
|
||||
If $n$ is larger, it can be pre-reduced modulo $k$, since $A_k(n)$
|
||||
only depends on the value of $n \bmod k$.
|
||||
|
||||
void arith_number_of_partitions_mpfr(mpfr_t x, ulong n)
|
||||
|
||||
Sets the pre-initialised MPFR variable $x$ to the exact value of $p(n)$.
|
||||
The value is computed using the Hardy-Ramanujan-Rademacher formula.
|
||||
|
||||
The precision of $x$ will be changed to allow $p(n)$ to be represented
|
||||
exactly. The interface of this function may be updated in the future
|
||||
to allow computing an approximation of $p(n)$ to smaller precision.
|
||||
|
||||
The Hardy-Ramanujan-Rademacher formula is given with error bounds
|
||||
in \cite{Rademacher1937}. We evaluate it in the form
|
||||
|
||||
$$p(n) = \sum_{k=1}^N B_k(n) U(C/k) + R(n,N)$$
|
||||
|
||||
where
|
||||
|
||||
$$U(x) = \cosh(x) + \frac{\sinh(x)}{x},
|
||||
\quad C = \frac{\pi}{6} \sqrt{24n-1}$$
|
||||
|
||||
$$B_k(n) = \sqrt{\frac{3}{k}} \frac{4}{24n-1} A_k(n)$$
|
||||
|
||||
and where $A_k(n)$ is a certain exponential sum. The remainder satisfies
|
||||
|
||||
$$|R(n,N)| < \frac{44 \pi^2}{225 \sqrt{3}} N^{-1/2} +
|
||||
\frac{\pi \sqrt{2}}{75} \left(\frac{N}{n-1}\right)^{1/2}
|
||||
\sinh\left(\pi \sqrt{\frac{2}{3}} \frac{\sqrt{n}}{N} \right).$$
|
||||
|
||||
We choose $N$ such that $|R(n,N)| < 0.25$, and a working precision
|
||||
at term $k$ such that the absolute error of the term is expected to be
|
||||
less than $0.25 / N$. We also use a summation variable with increased
|
||||
precision, essentially making additions exact. Thus the sum of errors
|
||||
adds up to less than 0.5, giving the correct value of $p(n)$ when
|
||||
rounding to the nearest integer.
|
||||
|
||||
The remainder estimate at step $k$ provides an upper bound for the size
|
||||
of the $k$-th term. We add $\log_2 N$ bits to get low bits in the terms
|
||||
below $0.25 / N$ in magnitude.
|
||||
|
||||
Using \code{arith_hrr_expsum_factored}, each $B_k(n)$ evaluation
|
||||
is broken down to a product of cosines of exact rational multiples
|
||||
of $\pi$. We transform all angles to $(0, \pi/4)$ for optimal accuracy.
|
||||
|
||||
Since the evaluation of each term involves only $O(\log k)$ multiplications
|
||||
and evaluations of trigonometric functions of small angles, the
|
||||
relative rounding error is at most a few bits. We therefore just add
|
||||
an additional $\log_2 (C/k)$ bits for the $U(x)$ when $x$ is large.
|
||||
The cancellation of terms in $U(x)$ is of no concern, since Rademacher's
|
||||
bound allows us to terminate before $x$ becomes small.
|
||||
|
||||
This analysis should be performed in more detail to give a rigorous
|
||||
error bound, but the precision currently implemented is almost
|
||||
certainly sufficient, not least considering that Rademacher's
|
||||
remainder bound significantly overshoots the actual values.
|
||||
|
||||
To improve performance, we switch to doubles when the working precision
|
||||
becomes small enough. We also use a separate accumulator variable
|
||||
which gets added to the main sum periodically, in order to avoid
|
||||
costly updates of the full-precision result when $n$ is large.
|
||||
|
||||
void arith_number_of_partitions(fmpz_t x, ulong n)
|
||||
|
||||
Sets $x$ to $p(n)$, the number of ways that $n$ can be written
|
||||
as a sum of positive integers without regard to order.
|
||||
|
||||
This function uses a lookup table for $n < 128$ (where $p(n) < 2^{32}$),
|
||||
and otherwise calls \code{arith_number_of_partitions_mpfr}.

||||

|

|

void arith_sum_of_squares(fmpz_t r, ulong k, const fmpz_t n)
|
||||
|
||||
Sets $r$ to the number of ways $r_k(n)$ in which $n$ can be represented
|
||||
as a sum of $k$ squares.
|
||||
|
||||
If $k = 2$ or $k = 4$, we write $r_k(n)$ as a divisor sum.
|
||||
|
||||
Otherwise, we either recurse on $k$ or compute the theta function
|
||||
expansion up to $O(x^{n+1})$ and read off the last coefficient.
|
||||
This is generally optimal.
|
||||
|
||||
void arith_sum_of_squares_vec(fmpz * r, ulong k, slong n)
|
||||
|
||||
For $i = 0, 1, \ldots, n-1$, sets $r_i$ to the number of
|
||||
representations of $i$ a sum of $k$ squares, $r_k(i)$.
|
||||
This effectively computes the $q$-expansion of $\vartheta_3(q)$
|
||||
raised to the $k$th power, i.e.
|
||||
|
||||
$$\vartheta_3^k(q) = \left( \sum_{i=-\infty}^{\infty} q^{i^2} \right)^k.$$

void mpfr_pi_chudnovsky(mpfr_t x, mpfr_rnd_t rnd)

Sets \code{x} to $\pi$, rounded in the direction \code{rnd}.
|
||||
|
||||
Uses the Chudnovsky algorithm, which typically is about four times
|
||||
faster than the MPFR default function. As currently implemented, the
|
||||
value is not cached for repeated use.
