課程概述 
Contents.
We introduce group representations for finite groups, compact groups, and locally compact groups. The later includes padic groups, adelic groups, i.e. automorphic representations of algebraic groups over global fields. We will use algebraic tools primarily. But we will also bring in tools from harmonic analysis, Haar integrals, complex analysis, and distribution theory. We will do classification of representations for classes of groups. Will also apply representation theory to problems arising and connected with other fields of mathematics, particularly number theory and arithmetic geometry. 
課程目標 
Representations of groups play a central role in mathematics. Great progress had been made in the last century which lead to solutions of many key problems in mathematics. Currently, the developments of representation theory of groups involves most active frontier researches. Our goal is to introduce students this very important field. This course is suitable for advanced undergraduates as well as beginning graduate students. It connects all the basic courses, algebra and analysis. It underlines to students the fact that combining all the fundamental tools previously learnt is essential for doing modern mathematics researches. 
課程要求 
Prerequisite: Linear Algebra, Algebra, Analysis.
We will start with five themes: modular representations, representations of symmetric groups, computing with induced representations, compact groups and harmonic analysis, a tale of two groups. Each student should choose at least one theme among the five. We make use the Overleaf platform on the webe sites where every student can write exercises, comments, discussions directly on the site at anytime, while the professor charging this course may also look closely at the progress of students on the Overleaf site and making comments.
