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.…

Representations of the modular shifted super Yangian $Y_{1∣1} (σ)$

Hao Chang, Ruiying Hou, Hui Wu

Let $Y_{1∣1}$ be the Yangian associated to the general linear Lie superalgebra $gl_{1∣1}$ , defined over an algebraically closed field $\mathbbm{k}$ of characteristic $p>…

Super Yangians in characteristic $2$

Hao Chang, Hongmei Hu

We define the super Yangian $Y_{m ∣ n}$ over a field $\mathbbm{k}$ of characteristic $2$ , and show that the super Yangian $Y_{m ∣ n}$ is a deformation of the super universal enveloping…

The center of modular shifted Yangians and parabolic generators

Hao Chang, Hongmei Hu

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