Title : Potentially crystalline deformation rings for certain shapes of colength one.

Abstract : : Current technique towards modularity lifting theorem relies on understanding the geometry of local deformation rings. In this talk, we introduce a way to construct potentially crystalline deformation rings for certain colength one case. This is a joint work with Daniel Le, Bao Le Hung, Stefano Morra, and Zicheng Qian.
