Abstract:

Broué and Rickard defined in their landmark papers from 1990 and 1996 the notions of an isotypy and a splendid equivalence between $p$-blocks of finite groups. Here, we define a notion of equivalence, which we call a $p$-permutation equivalence, that implies an isotypy and is implied by a splendid equivalence. Moreover, we study properties of $p$-permutation equivalences.
