Higher Hida theory for Hilbert modular varieties in the totally split case

Number Theory 2025-09-23 v3 Algebraic Geometry

Abstract

We study pp-adic properties of the coherent cohomology of some automorphic sheaves on the Hilbert modular variety XX for a totally real field FF in the case where the prime pp is totally split in FF. More precisely, we develop higher Hida theory \`{a} la Pilloni, constructing, for 0q[F:Q]0\leq q\leq [F:\mathbb{Q}], some modules MqM^q which pp-adically interpolate the ordinary part of the cohomology groups Hq(X,ωκ)H^q(X, \underline{\omega}^{\kappa}), varying the weight κ\kappa of the automorphic sheaf.
