Modular Forms in Pari/GP
Karim Belabas, Henri Cohen
We give theoretical and practical information on the Pari/GP modular forms package available since the spring of 2018. Thanks to the use of products of two Eisenstein series, this…
Expansions at Cusps and Petersson Products in Pari/GP
Henri Cohen
We begin by explaining how to compute Fourier expansions at all cusps of any modular form of integral or half-integral weight thanks to a theorem of Borisov-Gunnells and explicit e…
An Introduction to Modular Forms
Henri Cohen
In this course we introduce the main notions relative to the classical theory of modular forms. A complete treatise in a similar style can be found in the author's book joint with…
Computational Number Theory in Relation with L-Functions
Henri Cohen
We give a number of theoretical and practical methods related to the computation of L-functions, both in the local case (counting points on varieties over finite fields, involving…
