I am interested in any sources that can be helpful for learning the representation theory of real reductive groups. I am currently reading Wallach book, but I feel that I don't understand the subject properly and want to find an alternative.


1 Answer 1


First note that there is the book of Vogan (Representation Theory if real reductive groups) which discusses the case of $SL_2(\mathbb{R})$ on a very basic level. I think this is a good start. In my opinion the remainder of the book is not very accessible.

However for the whole theory I would recommend that you first look at the notes from the conference "Computational Theory of Real Reductive Groups"


Especially the notes from Adams and Vogan give a good introduction to the subject, don’t require much background and both are filled with examples.

Finally I should add Knapp's Book: Lie Groups Beyond an Introduction. At least the structure of real reductive groups (max. compact subgroups and so on) is discussed there.

In which direction to you want to go? Do you "really" want to do representation theory or are you planning to go to geometric representation theory?

  • $\begingroup$ Thank you very much for your answer. I am not quite sure what about the direction of my studies mainly because I don't know much about geometric representation theory. $\endgroup$

  • $\begingroup$ Anyway, if you are interested in learning geometric representation theory the you might find this interesting: mathoverflow.net/questions/160387/… $\endgroup$ Apr 12, 2014 at 12:40
