　　Abstract：Let B_0（G） be the principal block algebra of the group algebra kG of an infinitesimal group scheme G. We calculate the restricted Lie algebra structure of the first Hochschild cohomology of L:=H^1（B_0（G）， B_0（G））。As a consequence, we obtain a criterion for wildness of kG.

　　Title: On the finite W-superalgebras associated with minimal nilpotent elements

　　时间：2020/10/30 10:30-11:10，地点：1-301

　　Abstract：In this talk we will consider finite W-superalgebras associated with minimal nilpotent elements. We first introduce the explicit generators and their commutators of minimal finite W-superalgebras, and then study the corresponding highest weight modules. This is a joint work with Professor Bin Shu.
