Invariants and representations of the $Γ$ -graded general linear Lie $ω$ -algebras

R. B. Zhang

There is considerable current interest in applications of generalised Lie algebras graded by an abelian group $Γ$ with a commutative factor $ω$ . This calls for a systematic develop…

A polar Brauer category and Lie superalgebra representations

G. I. Lehrer, R. B. Zhang

We introduce a diagram category, study its structure, and investigate some of its applications to the representation theory of Lie algebras and Lie superalgebras. The morphisms of…
