| Jan 7, 2013 at 13:49 | comment | added | Jim Humphreys | @Bruce: Yes, the idea is basically the same for Green rings though I had the impression that split Grothendieck groups were defined explicitly in a more geometric framework. I still have to do some rechecking about origins and motivation. | |
| Jan 7, 2013 at 13:36 | comment | added | Bruce Westbury | I was going to point out that this concept for finite groups is known as the Green ring. Then I discovered that you were the reviewer for: MR0537496 (80e:20012) Alperin, J. L. Projective modules for SL(2,2n). J. Pure Appl. Algebra 15 (1979), no. 3, 219--234. | |
