Refinement of Tate's Discriminant Bound and Non-Existence Theorems for Mod $p$ Galois Representations
Non-existence is proved of certain continuous irreducible mod $p$ representations of degree 2 of the absolute Galois group of the rational number field. This extends previously known results, the improvement based on a refinement of Tate's discriminant bound.
