Abstract
For any algebraically closed eld k of positive characteristic p and any non negative integer n Kdened ideals TnA ? of the centre of a symmetric k-algebra A. We show that for derived equivalent algebras A and B there is an isomorphism of the centres of A and B mapping TnA ? to TnB ? for all n. Recently H ethelyi, Horv ath, K ulshammer and Murray showed that this holds for Morita equivalent algebras.
