Abstract

Let m be a positive integer and A an elementary abelian group of order q^r with r greater than or equal to 2 acting on a finite q'-group G. We show that if for some integer d such that 2^{d} is less than or equal to (r-1) the dth derived group of C_{G}(a) has exponent dividing m for any nontrivial element a in A, then G(d)G^{(d)} has {m,q,r}-bounded exponent and if γr1(CG(a))\gamma_{r-1}(C_G(a)) has exponent dividing m for any nontrivial element a in A, then γr1(G)\gamma_{r-1}(G) has {m,q,r}-bounded exponent.
