In this course, we will discuss the modulo p and p-adiclocal Langlands correspondence for GL_2(Q_p), which is established in recent years by Breuil,Colmez, Kisin, Paskunas, etc. 

We will firstly talk about modulo p representation theory of GL_2 of a local field F of residual characteristic p, with an emphasis on the caseF=Q_p. We then discuss the construction of a functor of Colmez relating representations of GL_2(Q_p) and representations of the absolute Galois group of Q_p, which plays a crucial role in the theory. Finally, we will pass to their deformation theory and explain the proof of the theoremthat Colmez’sfunctor realizes the p-adic local Langlands correspondence.





Background on representation theory, abstract algebra and algebraic number theory, particularly knowledge on local fields.
