Regular Time: 13:00-14:30 & 15:00-16:30 23/11, 30/11, 7/12, 21/12

This short course aims to give an introduction to some recent progress on mod p Langlands program and mod p Jacquet-Langlands program. We will mainly focus on the case of GL_2(Q_p).
We will discuss the following topics:
(i) Mod p representation theory of GL_2(Qp) and of quaternion algebra over Qp;
(ii) Serre weights in the quaternion algebra setting;
(iii) Galois deformation theory;
(iv) Gelfand-Kirillov dimension of admissible representations of p-adic groups;
(v) Scholze’s functor and some vanishing result.
Prerequisite:
Basic representation theory of p-adic groups; basic facts on local fields and p-adic analytic groups.
