Ha­rish-Chandra Se­mi­nar

Every given semester this seminar focuses on a particular theme in the representation theory and the harmonic analysis of real reductive groups.

Topic Summer 2023: A main theme will be the Whittaker Plancherel theorem as stated by Harish-Chandra. Another topic will be Harish Chandra's approach to the Plancherel theory of SL(2,R), which will be discussed in detail. Furthermore students will give talks on the Harish-Chandra isomorphism.

The seminar will take place in D 1 320 every Thursday from 4.15 to 6 p.m.
