Green–Héthelyi–Lilienthal reformulation of Oliver's p-group conjecture

From papers

Let pp be an odd prime and let GG be a finite pp-group. Let VV be a faithful Fp[G]\mathbb{F}_p[G]-module. The module VV is an FF-module for GG if there is a nontrivial elementary abelian subgroup EGE\le G such that

ECV(E)V.|E|\,|C_V(E)|\ge |V|.

Let Ω1(Z(G))\Omega_1(Z(G)) denote the subgroup of central elements of order dividing pp.

Green–Héthelyi–Lilienthal reformulation. If VV is an FF-module, then there is an element 1gΩ1(Z(G))1\ne g\in\Omega_1(Z(G)) such that the minimal polynomial of the action of gg on VV divides

(x1)p1.(x-1)^{p-1}.

This is presented as a reformulation of Oliver's p-group conjecture. The source does not state a resolution, so its status is recorded as open.
