Title: Intersections of irreducible components of the Emerton-Gee stack for GL_2
Speaker: Kalyani Kansal (Johns Hopkins)
Abstract: Let K be a finite extension of Q_p. In a 2020 paper, Caraiani, Emerton, Gee, and, Savitt constructed a moduli stack of two dimensional mod p representations of the Galois group of K. We compute criteria for codimension one intersections of the irreducible components of this stack, and interpret them in sheaf-theoretic terms.
