Weyl groupoids and superalgebraic sets
Ian M. Musson
This paper is a contribution to the study of the geometry of algebras related the Weyl groupoid initiated in \cite{M22}. The Nullstellensatz gives a bijection between radical ideal…
On the geometry of algebras related to the Weyl groupoid
Ian M. Musson
Let be an algebraically closed field of characteristic zero. Let be a finite dimensional classical simple Lie superalgebra over or $\mathf…
Shapovalov Elements For $U_q(\mathfrak{sl}(N+1))
Stefan Catoiu, Ian M. Musson
For a simple Lie algebra, Shapovalov elements give rise to highest weight vectors in Verma modules. The usual construction of these elements uses induction on the length of a certa…
Explicit expressions for \vSapovalov elements in Type A
Ian M. Musson
We give explicit expressions for \vSapovalov elements in Type A Lie algebras and superalgebras. Explicit expressions were already given in arXiv:1710.10528 Section 9, using non-com…
