SUMMARY:Workshop / Seminar:GLNT: Minimal lifts of mod-3 modular forms
DESCRIPTION:Abstract: Serre's conjecture has two parts: a modularity part — that predicts which mod-ell Galois representations come from a modular form — and a minimal-lifting part — that predicts the minimal weight\, level\, and character of the modular form. Not long after formulating the conjecture\, Serre found a counterexample to the minimal-lifting part for small values of ell (ell<5)\, where the character part of the prediction is wrong. In this talk\, I'll discuss a variant of the minimal-lifting conjecture where the nebentypus character is replaced by the character used to define a supercuspidal representation. I will show that\, in this case\, even for ell=3\, there is no obstruction to finding minimal lifts. This is joint work with Patrick Allen.
