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…
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…
Borel subalgebras of Cartan Type Lie Algebras
Ke Ou, Bin Shu
Let be Jacobson-Witt algebra over algebraic closed field with positive characteristic It is difficult to classify all Borel subalgebras of …
