摘要
本文研究了扩张的圈Schrodinger-Virasoro代数,给出了这类李代数的所有二上同调群,同时得到了这类李代数的所有泛中心扩张.
In this paper, we study the extended loop Schrodinger-Virasoro algebras and give the second cohomology groups of the extended loop Schrodinger-Virasoro algebras are determined. Moreover, we obtain the universal central extensions of the extended loop Schrodinger-Virasoro algebras are given.
