Fernando Rodriguez-Villegas, containing a huge number of sample
[get there]. A series
of introductory lectures about number theory, with a bias towards explicit
computations, by William Stein. It contains an introduction to GP and many
The SIAM 100-Digit Challenge book is a gourmet feast in ten courses on
(high precision) numerical analysis. Some GP scripts are available on the
book web site.
Series, products, integrals

indefinite summation of rational functions
using Gosper's algorithm (by Ralf
- [get it] Zeroes of Hecke L-functions (by
- [get it] (OBSOLETE). Compute values of Hurwitz zeta and Dirichlet
L-series, partial fraction decomposition of a rational
function F, as well as
(by Henri Cohen). The functionality is available in pari-2.10.
- [get it] (OBSOLETE) values of motivic L-functions (by
Tim Dokchitser). The functionality is available in pari-2.7.
- [get there] descent via isogeny on elliptic curves which have a rational
torsion point of order N (by V. Flynn and C. Grattoni).
- [get it] torsion over number fields, isogeny graphs, divisors, Vélu
formulae (by François Brunault).
- [get it]. 2-descent over number fields. Works quite well for fields of
degree less than 3, and is well suited for handling several quadratic twists
of a common curve. It gives an alternative to John Cremona's mwrank even over
Q. Of independant interest, the submodule
qfsolve solves efficiently any ternary quadratic equation, even
not in diagonal (Legendre) form (by Denis Simon).
Compute Heegner points, p-adic or complex (by Peter Green).
- [get it].
Derived periods and the Mazur-Tate circle pairing (by
Henri Darmon and Massimo Bertolini).

variants of most cryptographic pairing, by Jérome Milan

Joe Wetherell, William Stein, Dominique Bernardi, Bernadette Perrin-Riou and
Karim Belabas. The functionality is available in pari-2.9.

group structure over ℤ/pℤ). The functionality is available
[get it] (OBSOLETE). The 'ellsea' package, an implementation of the
Schoof-Elkies-Atkin algorithm over a prime field,

fullfactor package, implementing a large set of
integer factorization helpers for integers of a special form (includes tables
from the Cunningham project).
A page on diagonal quartic surfaces, containing GP scripts and PARI
programs (Picard groups and point counting); by Martin Bright.
[get there]. Large library of GP routines, developed by
Fernando Rodriguez-Villegas and
Ariel Pacetti: quaternion algebras, binary quadratic forms, conics,
jacobian of cubics/quartics, Igusa invariants, Dedekind's eta function on CM
points, skew-symetric matrices, elliptic units, elliptic dilogarithm, p-adic
gamma function, Brandt matrices, lifting matrices, polynomials in several
variables, vector handling routines, various factoring algorithms over Z
(p-1, Lenstra), K-theory of number fields and zeta values
