Navarro's Galois Alperin weight conjecture for finite groups

From papers

Let pp be a prime, let kk be an algebraic closure of Fp\mathbb{F}_p, let Γ=Gal(k/Fp)\Gamma={\rm Gal}(k/\mathbb{F}_p), let GG be a finite group, and let OG\mathcal{O}_G be its pp-orbit category. Let S(kG)\mathcal{S}(kG) and W(kOG)\mathcal{W}(k\mathcal{O}_G) denote the sets of isomorphism classes of simple modules and weights, respectively. Navarro's conjecture. For any finite group GG, there exists a bijection

S(kG)W(kOG)\mathcal{S}(kG)\to\mathcal{W}(k\mathcal{O}_G)

commuting with the action of Γ\Gamma. This is the Galois refinement of Alperin's weight conjecture; the paper uses it as the finite-group case of its category-algebra formulation.
