Quantization of generalized Virasoro-like algebras
Guang'ai Song, Yucai Su, Yuezhu Wu
In a recent paper by the authors, Lie bialgebras structures of generalized Virasoro-like type were considered. In this paper, the explicit formula of the quantization of generalize…
Classification of Z^2-graded modules of the intermediate series over a Lie algebra of Block type
Xiaoqing Yue, Yucai Su
Let L be the Lie algebra of Block type over a field F of characteristic zero, defined with basis {L_{i,j} | i,j\in Z} and relations [L_{i,j},L_{k,l}]=((j+1)k-(l+1)i)L_{i+k,j+l}. Th…
Classification of modules of the intermediate series over Ramond N=2 superconformal algebras
Jiayuan Fu, Qifen Jiang, Yucai Su
In this paper, we first discuss the structure of the Ramond N=2 superconformal algebras. Then we also classify the modules of the intermediate series over Ramond N=2 superconformal…
Second homology groups and universal coverings of Steinberg Leibniz algebras of small characteristic
Qifen Jiang, Ran Shen, Yucai Su
It is known that the second Leibniz homology group of the Steinberg Leibniz algebra is trivial for . In this paper, we determine $HL_2(stl_n(R)…
Hamiltonian type Lie bialgebras
Bin Xin, Guang'ai Song, Yucai Su
We first prove that, for any generalized Hamiltonian type Lie algebra , the first cohomology group is trivial. We then show that all Lie bialgebra structure…
