Large $${\varvec{p}}^{\prime }$$ p ′ -orbits for $${\varvec{p}}$$ p -nilpotent linear groups

Abstract

Let G be a p-nilpotent linear group on a finite vector space V of characteristic p. Suppose that |G||V| is odd. Let P be a Sylow p-subgroup of G. We show that there exist vectors \(v_1\) and \(v_2\) in V such that \(C_G(v_1) \cap C_G(v_2)=P\). A striking conjecture of Malle and Navarro offers a simple global criterion for the nilpotence (in the sense of Broue and Puig) of a p-block of a finite group. Our result implies that this conjecture holds for groups of odd order.
