Alperin's "Sylow Intersections and Fusion" (MR0215913; DOI: 10.1016/0021-8693(67)90005-1) is a nice group theoretic introduction to some of the key ideas behind fusion. It is a more precise version of Sylow's conjugacy theorem. Linckelmann's introduction (MR2336638) is one of the easiest ways to read the category theoretic version of fusion. Alperin's Local Representation Theory textbook introduces the Brauer subpairs theory nicely; that is the other main source of fusion systems. | |

But there's no obvious reason (to me, anyway) that there shouldn't be an extension even to finite groupoids. | |
