Resumen de A McKay bijection for projectors
If F is a saturated formation of groups, we define a canonical subset IrrF′(G) of the irreducible complex characters of a finite solvable group G. If H is an F-projector of G, we show that |IrrF′(G)|=|Irr(NG(H)/H′)|, where H′=[H,H] is the derived subgroup of H. In particular, if F is the class of p-groups, this reproves the solvable case of the celebrated McKay conjecture.
