Universal central extensions of $s l_{m ∣ n}$ over $Z /2 Z$ -graded algebras

Hongjia Chen, Jie Sun

We study central extensions of the Lie superalgebra $s l_{m ∣ n} (A)$ , where $A$ is a $Z /2 Z$ -graded superalgebra over a commutative ring $K$ . The Steinberg Lie superalgebra $st_{m|n}(A…

Tensor product weight modules over the Virasoro algebra

Hongjia Chen, Xiangqian Guo, Kaiming Zhao

The tensor product of highest weight modules with intermediate series modules over the Virasoro algebra was discussed by Zhang [Z] in 1997. Since then the irreducibility problem fo…
