Quasi-Whittaker modules

Cunguang Cheng, Wenting Gao, Shiyuan Liu +2

In this paper, a general setting is proposed to define a class of modules over nonsemisimple Lie algebras $g$ induced by a nonperfect ideal $p$ . This class of…

Simple smooth modules over the Lie algebras of polynomial vector fields

Zhiqiang Li, Cunguang Cheng, Shiyuan Liu +3

Let $g := Der (C [t_{1}, t_{2}, \dots, t_{n}])$ and $L := Der (C [[t_{1}, t_{2}, \dots, t_{n}]])$ be the Witt Lie algebras. Clearly, $g$ i…
