The $E_{6}$ Restricted Hyperplane Arrangement and its $E_{7}$ Shadow: Weyl Transport on a Minuscule Bruhat Poset

Saber Ahmed, Mboyo Esole

We study the restricted fan cut inside the dual fundamental Weyl chamber by the weights of a $27$ -dimensional minuscule representation of $E_{6}$ ; the two such representations are du…

Highest Weight Modules Over The Quantum Periplectic Superalgebra of Type $P$

Saber Ahmed, Dimitar Grantcharov, Nicolas Guay

In this paper, we begin the study of highest weight representations of the quantized enveloping superalgebra $U_{q} p_{n}$ of type $P$ . We introduce a Drinfeld-…
