Abstract:
I will show that the L-function of a 2-dimensional complex Galois representation is either modular or has infinitely many poles. In particular, Artin's conjecture for a given representation implies modularity, with no twists needed. The technique used in the proof may be extended to give a new Weil-type converse theorem.
