Title:  Some recent progress in mod p Langlands program for GL_2

 

 

Abstract: In this series of talks, I will give a survey on some recent progress in the mod p Langlands program for GL_2(K), where K is a finite unramified extension of Qp. The talks are based on joint work with Breuil-Herzig-Morra-Schraen and with Wang. 

In the first talk, I will recall the mod p Langlands correspondence in the case of GL_2(Qp), including the classification of Barthel-Livné and Breuil, and the construction of Colmez’s functor. In the second talk, I will talk about the Gelfand-Kirillov dimension of admissible smooth representations of GL_2(K) coming from mod p cohomology of Shimura curves, and the relation to p-adic Langlands. In the last talk I will explain a generalization of Colmez’s functor in the case of GL_2(K).
