Feb 19, 2011 at 16:52 comment added Johannes Hahn But one has to say that Alperin covers only a small part of modular representation theory, in particular block theory. There is nothing about decomposition theory. Also everything is written in the language of modules, but some results become more clearer if expressed for example in terms of central idempotents. After reading Alperin's book for example you may have a hard time understanding what Brauers main theorems as listed on wikipedia have to do with the three theorems you learned from Alperin...
