2-Cocycles of Deformative Schrödinger-Virasoro Algebras
arXiv:0801.2210
Abstract
In a series of papers by Henkel, Roger and Unterberger, Schrödinger-Virasoro algebras and their deformations were introduced and investigated. In the present paper we determine the 2-cocycles of a class of deformative Schrödinger-Virasoro algebras.
