Aug 19, 2012 at 12:22 | comment | added | Alexander Chervov | Q2: Take P=7-Sylow. V_3a, V_3b are exeptional ? And V_1, V_6,V_8 not ? Ind_{Sylow 7} = V_1 + V_7+ 2 V_8, corresponds to your answer like this: for V_1 we have 1=0*7+1 so k+$\epsilon$ = 1, so multiplicity is 1, and for V_6 we have +1-1=0 - so zero multiplicit, for V_8 we have +1+1 = 2 so multiplicity is 2. And about V_7 it is the first sentence 7/7=1. Is it correct ? | |
