Lie bialgebra structures on extended Schrodinger-Virasoro Lie algebra

arXiv:1004.3650

Abstract

In this paper, Lie bialgebra structures on the extended Schrodinger-Virasoro Lie algebra are classified. It is obtained that all the Lie bialgebra structures on L are triangular coboundary. As a by-product, it is derived that the first cohomology group is trivial.
