2-McKay conjecture for 2-representations
2-McKay conjecture for 2-representations
Let be a finite group, let be a fixed prime, let be the centre of , let be a Sylow -subgroup, and let be its normaliser. Let be the group of automorphisms of that preserve and restrict to the identity on . For each character , let
2-McKay conjecture. For each character , the 2-representations and of are isomorphic. This is a 2-representation-theoretic strengthening of the McKay comparison between and the normaliser of a Sylow subgroup, motivated by the notion of McKay-goodness.
