Representations of Finite Groups
As we are mainly interested in continuous groups like SO(3) etc., this topic plays no central rôle in our text. But here we can learn a lot about how representation theory works. Thus we present the basic facts. We will not do it by using the abstract notions offered by modern algebra (as for instance in [FH]), where eventually the whole theory can be put into the nutshell of one page. Instead we follow very closely the classic presentation from the first pages of Serre’s book [Se].
