Refined inverse Galois problem for abelian varieties

Fix a prime number pp and let GW2dG\subset W_{2d} be a transitive subgroup containing the complex conjugation element. The weighted permutation representation associated to an abelian variety AA is the representation whose image is compared with GG below, and wAw_A denotes the corresponding conjugating element. Refined inverse Galois conjecture. There exists an integer r1r\geq 1 and a simple abelian variety A/FprA/\mathbf{F}_{p^r} of dimension dd such that GG is wAw_A-conjugate to the image of the weighted permutation representation associated to AA, and AA may be taken to be ordinary. In particular, GG is isomorphic to the Galois group of some abelian variety AA. This is presented as a slight refinement of a conjecture of Dupuy, Kedlaya, Roe, and Vincent concerning which groups arise as Galois groups of abelian varieties. The supplied context does not state whether the conjecture has been resolved.
