The center of the modular super Yangian $Y_{m ∣ n}$

Hao Chang, Hongmei Hu

The present paper is devoted to studying the super Yangian $Y_{m ∣ n}$ associated to the general linear Lie superalgebra $gl_{m ∣ n}$ over a field of positive characteristic…

Tensor products of the defining representations over the Witt algebra in positive characteristic

Hao Chang, Yu-Feng Yao

Let $A (1) := k [X] / (X^{p})$ be the natural representation of the Witt algebra $W (1)$ over an algebraically closed field of prime characteristic $p > 3$ . In this note, we decompose the $W(…

Borel subalgebras of the Witt algebra $W_{1}$

Yu-Feng Yao, Hao Chang

Let $F$ be an algebraically closed field of characteristic $p > 3$ , and $⋙$ the $p$ -dimensional Witt algebra over $F$ . Let $N$ be the nilpotent cone of $⋙$ .…
