Galois Alperin weight conjecture for a finite group
Galois Alperin weight conjecture for a finite group
Fix a prime and a finite group . Let be the Galois automorphism group associated with the -modular system in the source. Let be the set of -weights of , with the action of induced by Galois automorphisms and group automorphisms. Galois Alperin weight conjecture for . There exists an -equivariant surjective map
such that maps only -conjugate weights to a common Brauer character. This formulation is equivalent to requiring a well-defined equivariant bijection between -orbits of weights and irreducible Brauer characters. The source presents it as a conjecture, and no general resolution is stated.
