摘  要：It is known that the class of self-injective algebras over algebraically closed fields 

is closed under derived equivalences. In this talk, we extend this result to any field. More 

precisely, we show that the Nakayama permutations of two derived equivalent self-injective

 Artin algebras are conjugate.  With this new and elementary approach, we show that the 

classes of weak symmetry and self-injective algebras respectively, over any field，are 

closed under derived equivalences. The talk is based on a joint work with Professor 

Changchang Xi.
