Abstract: |
In this paper, we study the extended loop Schrödinger-Virasoro algebras and give the second cohomology groups of the extended loop Schrödinger-Virasoro algebras are determined. Moreover, we obtain the universal central extensions of the extended loop Schrödinger-Virasoro algebras are given. |
