Quantization of Schrödinger-Virasoro Lie algebra
Yucai Su, Lamei Yuan
In this paper, we use the general quantization method by Drinfel'd twists to quantize the Schrödinger-Virasoro Lie algebra whose Lie bialgebra structures were recently discovered b…

Generalised Jantzen filtration of Lie superalgebras I
Yucai Su, R. B. Zhang
A Jantzen type filtration for generalised Varma modules of Lie superalgebras is introduced. In the case of type I Lie superalgebras, it is shown that the generalised Jantzen filtra…
