Irreducible tensor product modules over the affine-Virasoro algebra of type

Qiu-Fan Chen, Yu-Feng Yao

In this paper, we construct a class of non-weight modules over the affine-Virasoro algebra of type by taking tensor products of irreducibles defined in [Q. Chen, J. Han, Non-…

On structure of graded restricted simple Lie algebras of Cartan type as modules over the Witt algebra

Ke Ou, Yu-Feng Yao

Any graded restricted simple Lie algebra of Cartan type contains a subalgebra isomorphic to the Witt algebra over a field of prime characteristic. As some analogue of study on bran…

2-local derivations on the Jacobson-Witt algebras in prime characteristic

Yufeng Yao, Kaiming Zhao

This paper initiates the study of 2-local derivations on Lie algebras over fields of prime characteristic. Let be a simple Jacobson-Witt algebra over a field o…

On enhanced reductive groups (I): Parabolic Schur algebras and the dualities related to degenerate double Hecke algebras

Bin Shu, Yunpeng Xue, Yufeng Yao

An enhanced algebraic group $\uG$ of $G=\GL(V)$ over $\bbc$ is a product variety $\GL(V)\times V$, endowed with an enhanced cross product. Associated with a natural tensor represen…
