Abstract

In this paper we will prove that if GG is a finite group, XX a subnormal subgroup of XF(G)X F^*(G) such that XF(G)X F^*(G) is quasinilpotent and YY is a quasinilpotent subgroup of NG(X)N_G(X), then Y F^*(N_G(X}) is quasinilpotent if and only if YF(G)Y F^*(G) is quasinilpotent. Also we will obtain that FGF^*{G} controls its own fusion in GG if and only if G=FGG=F^*{G}.
