Simple modules over truncated current Lie algebras of the Witt algebra

Hao Chang, Ruiying Hou, Jinxin Hu

Let $k$ be an algebraically closed field of characteristic $p > 3$ , and let $W$ denote the $p$ -dimensional Witt algebra, the first example of a non-classical simple Lie algebra.…

The center of modular shifted Yangians and parabolic generators

Hao Chang, Hongmei Hu

This paper is devoted to the study of the shifted Yangian $Y_{n} (I ¨ )$ associated to the general linear Lie algebra $gl_{n}$ over a field of positive characteristic. We obtai…
