We give a survey of methods used to connect the study of ternary diophantine equations to modern techniques coming from the theory of modular forms.

Computing modular degrees using L -functions

Christophe Delaunay (2003)

Journal de théorie des nombres de Bordeaux

Similarity:

We give an algorithm to compute the modular degree of an elliptic curve defined over . Our method is based on the computation of the special value at s = 2 of the symmetric square of the L -function attached to the elliptic curve. This method is quite efficient and easy to implement.
