Computing congruences of modular forms and Galois representations modulo prime powers
Taixes Ventosa, Xavier; Wiese, Gabor (2010)
Article
Accés obertThis article starts a computational study of congruences of modular forms and modular Galois representations modulo prime powers. Algorithms are described that compute the maximum integer modulo which two monic coprime ... -
Congruences between modular forms and lowering the level mod l^n
Dieulefait, Luis Victor; Taixes Ventosa, Xavier (2009)
Article
Accés obertIn this article we study the behavior of inertia groups for modular Galois mod ℓn representations and in some cases we give a generalization of Ribet’s lowering the level result.
