Galois Alperin weight conjecture
Galois Alperin weight conjecture
Fix a prime and a finite group . Let be the finite abelian group of Galois automorphisms associated with the -modular system described in the source. Let be the irreducible Brauer characters of , and let be the set of -weights of . The group acts on both sets, and hence on the set of -orbits . Galois Alperin weight conjecture. For any finite group , there exists an -equivariant bijection
This strengthens Alperin's weight conjecture by requiring compatibility with Galois and group automorphisms. It is known for -solvable groups in the strengthened form, but remains open in general.
