A refinement of Serre's conjecture
[ 講演概要 ]
Gaitsgory-Raskin proved a remarkable theorem: in the function field setting, a certain natural vector space of (everywhere unramified) automorphic forms for GL_n is isomorphic to the global sections of the dualizing sheaf on a natural stack of Langlands parameters. I will describe an attempt to translate the statement of this theorem to the number field context, in the setting of mod p automorphic forms. The resulting conjectural statement is a variant of conjectures of Emerton-Zhu; for GL_2 it is a refinement of Khare-Wintenberger's theorem (formerly, Serre's conjecture) relating modular forms and Galois representations mod p.
