We give explicit actions of Drinfeld generators on Gelfand–Tsetlin bases of super Yangian
modules associated with skew Young diagrams. In particular, we give another proof that …

Invariants and reduced matrix elements associated with the Lie superalgebra gl (m| n)

We present an overview of characteristic identities for Lie algebras and superalgebras. We
outline methods that employ these characteristic identities to deduce matrix elements of …

Parabosons, parafermions and representations of ℤ2× ℤ2-graded Lie superalgebras

NI Stoilova, J Van der Jeugt - Journal of Physics: Conference …, 2019 - iopscience.iop.org
For a set of m parafermion operators and n paraboson operators, there are two nontrivial
ways to unify them in a larger algebraic structure. One of these corresponds to the …

Super tableaux and a branching rule for the general linear Lie superalgebra

S Clark, YN Peng… - Linear and Multilinear …, 2015 - Taylor & Francis
In this note, we formulate and prove a branching rule for simple polynomial modules of the
Lie superalgebra. Our branching rules depend on the conjugacy class of a Borel …
