摘　　要：假设F是特征为0的域,Г是F上的加法子群,域F上的某个元s满足s ■Г但2s∈Г,本文定义了一类无限维李代数,称之为广义扩张的Schrddinger-Virasoro代数W[Г,s].本文确定了W[Г,s]的所有导子代数.Let F be a field of characteristic 0,Гan additive subgroup of F, s ∈ F satisfying s ■Гand 2s ∈Г. We define a class of infinite-dimensional Lie algebras which are called generalized extended Schrodinger-Virasoro algebras W[Г,s]In this paper, derivation algebras of W[Г,s] are completely determined.

关 键 词：Schrodinger-Virasoro代数:同调群 导子
