Tensor products of the defining representations over the Witt algebra in positive characteristic
Hao Chang, Yu-Feng Yao
Let be the natural representation of the Witt algebra over an algebraically closed field of prime characteristic . In this note, we decompose the $W(…
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…
Whittaker modules for the planar Galilean conformal algebra and its central extension
Qiufan Chen, Yufeng Yao, Hengyun Yang
Let be the planar Galilean conformal algebra and be its universal central extension. Then (resp. ) ad…
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…
