Inclusions between p-bounded crystalline loci in dimension two

Kalyani Kansal, Brandon Levin, David Savitt

Let p be an odd prime and K/Qp a finite unramified extension of degree f > 1. Let Z(r) be the reduced special fiber of the Emerton-Gee stack of two-dimensional crystalline represen…

Non-generic components of the Emerton-Gee stack for

Kalyani Kansal, Ben Savoie

Let be a finite unramified extension of with . We study the extremely non--generic irreducible components in the reduced part of the Emerton--Gee stack fo…

Irregular loci in the Emerton-Gee stack for GL_2

Rebecca Bellovin, Neelima Borade, Anton Hilado +5

Let K/Q_p be unramified. Inside the Emerton-Gee stack X_2, one can consider the locus of two-dimensional mod p representations of the absolute Galois group of K having a crystallin…

Codimension one intersections between components of the Emerton-Gee stack for

Kalyani Kansal

Let be a fixed odd prime, and let be a finite extension of with ring of integers . The Emerton-Gee stack for is a stack of $(φ…

Smoothness of components of the Emerton-Gee stack for

Anthony Guzman, Kalyani Kansal, Iason Kountouridis +2

Let be a finite unramified extension of , where . [CEGS22b] and [EG23] construct a moduli stack of two dimensional mod representations of the absolute Ga…
