Lie bialgebras of generalized Virasoro-like type
Yuezhu Wu, Guang'ai Song, Yucai Su
In two recent papers by the authors, all Lie bialgebra structures on Lie algebras of generalized Witt type are classified. In this paper all Lie bialgebra structures on generalized…

Verma modules over a Block Lie algebra
Qifen Jiang, Yuezhu Wu
Let B be the Lie algebra with basis {L_{i,j},C|i,j\in Z} and relations [L_{i,j},L_{k,l}]=((j+1)k-i(l+1))L_{i+k,j+l}+iδ_{i,-k}δ_{j+l,-2}C, [C,L_{i,j}]=0. It is proved that an irredu…
