Potentially Crystalline Deformation Rings for Ordinary Galois Representations
Chol Park ( Korean Institute for Advanced Study )


Abstract: Let be an upper-triangular Galois representation satisfying certain genericity assumptions. We discuss a way to prove a local deformation ring parameterizing potentially crystalline lifts of with certain fixed Hodge--Tate weights and Galois type is formally smooth. This is a joint work with Suh Hyun Choi and Zicheng Qian.
