Bimodule and twisted representation of vertex operator algebras

Qifen Jiang, Xiangyu Jiao

In this paper, for a vertex operator algebra $V$ with an automorphism $g$ of order $T,$ an admissible $V$ -module $M$ and a fixed nonnegative rational number $n\in\frac{1}{T}\Bbb{Z}…

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 $H L_{2} (s t l_{n} (R))$ of the Steinberg Leibniz algebra $s t l_{n} (R)$ is trivial for $n \geq 5$ . In this paper, we determine $HL_2(stl_n(R)…

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…
