On the geometric Serre weight conjecture for Hilbert modular forms
Abstract
Let be a prime, be a totally real field in which is unramified and be a totally odd, irreducible, continuous representation. The geometric Serre weight conjecture formulated by Diamond and Sasaki can be viewed as a geometric variant of the Buzzard-Diamond-Jarvis conjecture, where they have the notion of geometric modularity in the sense that arises from a mod Hilbert modular form and algebraic modularity in the sense of Buzzard-Diamond-Jarvis. Diamond and Sasaki conjecture that if is geometrically modular of weight and lies in the minimal cone, then is algebraically modular of the same weight, where is the set of embeddings from into . We prove the conjecture without parity hypotheses for real quadratic fields in which is inert, and for totally real fields in which totally splits.
