ABSTRACT
Let K be an arbitrary permutation group on a finite set Ω. Let G = H≀K be the corresponding permutational wreath product of a group H by K. It is proved that every Coleman automorphism of G is inner whenever H is either an almost simple group or a p-constrained group with for some prime p. In particular, the normalizer conjecture holds for such groups G. Other positive results regarding the normalizer conjecture are also obtained. Our results extend some known ones.
