On restricted Rota-Baxter Lie algebras of arbitrary weight
Yunnan Li, Ke Ou
Recently, Ehret and Gilliers introduced the notion of a (trivially) restricted post-Lie algebra, recovering the concepts of a restricted Lie algebra and a restricted pre-Lie algebr…
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…
On Chevalley restriction theorem for semi-reductive algebraic groups and its applications
Ke Ou, Bin Shu, Yu-Feng Yao
An algebraic group is called semi-reductive if it is a semi-direct product of a reductive subgroup and the unipotent radical. Such a semi-reductive algebraic group naturally arises…
Block Basis for Coinvariants of Modular Pseudo-reflection Groups
Ke Ou
As a sequel of \cite{Ou}, in this shot note, we investigate block basis for coinvariants of finite modular pseudo-reflection groups. We are particularly interested in the case wher…
Modular Invariants for Some Finite Pseudo-Reflection Groups
Ke Ou
In this paper, we determine the modular invariants of finite modular pseudo-reflection subgroups of the finite general linear group acting on the tensor product…
Block Degeneracy for Graded Lie Superalgebras of Cartan Type
Ke Ou
Let be an algebraically closed field of characteristic In this short note, we illustrate a class of Lie superalgebras over such that the catego…
