On p-permutation equivalences between direct products of blocks (2402.12751v1)
Published 20 Feb 2024 in math.GR
Abstract: We extend the notion of a p-permutation equivalence to an equivalence between direct products of block algebras. We prove that a p-permutation equivalence between direct products of blocks gives a bijection between the factors and induces a p-permutation equivalence between corresponding blocks.
