Weight elimination in Serre-type conjectures

Number Theory 2019-12-19 v4

Abstract

We prove the weight elimination direction of the Serre weight conjectures as formulated by Herzig for forms of U(n)U(n) which are compact at infinity and split at places dividing pp in generic situations. That is, we show that all modular weights for a mod pp Galois representation are contained in the set predicted by Herzig. Under some additional hypotheses, we also show modularity of all the "obvious" weights.
