1-cocycles of the Witt algebra with coefficients in tensor product of modules
Shoulan Gao, Dong Liu, Yufeng Pei
In this paper, we classify 1-cocycles of the Witt algebra with coefficients in the tensor product of two arbitrary tensor density modules. In a special case, we recover a theorem o…
Lie bialgebra structures on the twisted Heisenberg-Virasoro algebra
Dong Liu, Yufeng Pei, Linsheng Zhu
In this paper we investigate Lie bialgebra structures on the twisted Heisenberg-Virasoro algebra. With the classifications of Lie bialgebra structures on the Virasoro algebra, we d…
The derivations, central extensions and automorphism group of the Lie algebra
Shoulan Gao, Cuipo Jiang, Yufeng Pei
In this paper, we study the derivations, central extensions and the automorphisms of the infinite-dimensional Lie algebra W which appeared in [8] and Dong-Zhang's recent work [22]…
Structure of the extended Schrodinger-Virasoro Lie algebra
Shoulan Gao, Cuipo Jiang, Yufeng Pei
In this paper, we study the derivations, the central extensions and the automorphism group of the extended Schrodinger-Virasoro Lie algebra, introduced by J. Unterberger in the con…
