Abstract: We associate with any $ p$-block of a finite group a Grothendieck ring of certain $ p$-permutation bimodules. We extend the notion of $ p$-permutation equivalences introduced by Boltje and Xu (2006) to source algebras of $ p$-blocks of finite groups. We show that a $ p$-permutation equivalence between two source algebras $ A$, $ B$ of blocks with a common defect group and same local structure induces an isotypy.
