| 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. |
| Key words: Schrödinger-Virasoro algebra 2-cocycle central extension |
