Topics in representation theory (Spring 2020)

PKU, Yanyuan campus. Course ID: 00102930.

The main topic is Deligne-Lusztig theory for the characters of finite groups of Lie type. Basic backgrounds in representation theory are assumed. The grading is based on the homeworks PDF.

Main reference: F. Digne, J. Michel, Representations of Finite Groups of Lie Type (Cambridge University Press, 1991). The notes will appear elsewhere.

Modular forms and number theory (Fall 2019)

PKU, Yanyuan campus. The course will presumably be based on my notes. [Take-home Exams]

PKU, Yanyuan campus. Part of the Enhanced Program for Graduate Study. [Exercises + Exam]

Undergraduate seminar on algebra (Fall 2018)

PKU, Yanyuan campus. On Fridays 10 - 12 at Quan 29 (somewhat irregularly).

The topics are selected from E. Bombieri and W. Gubler. Heights in Diophantine geometry. Cambridge University Press (2006), together with the relevant materials from algebraic number theory and algebraic geometry.
