The inductive Alperin weight condition for finite categories
The inductive Alperin weight condition for finite categories
Let be a prime, let be an algebraic closure of , and let be a finite category. Let denote its automorphism group. If is an EI-category, let be a central idempotent of and let denote its stabiliser. Inductive Alperin weight condition. (i) For any finite category , there exists a bijection
commuting with the action of . (ii) For any finite EI-category and any central idempotent of , there exists a bijection
commuting with the action of . This is the category-algebra extension proposed after the finite-group inductive condition; the paper does not report a resolution.
