The Restricted Hyperplane Arrangement and its 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 -dimensional minuscule representation of ; the two such representations are du…
Convexity of Neural Codes with Four Maximal Codewords
Saber Ahmed, Natasha Crepeau, Gisel Flores +3
Place cells are neurons that act as biological position sensors, associated with and firing in response to regions of an environment to situate an organism in space. These associat…
Identifiability of directed-cycle and catenary linear compartment models
Saber Ahmed, Natasha Crepeau, Paul R. Dessauer +6
A parameter of a mathematical model is structurally identifiable if it can be determined from noiseless experimental data. Here, we examine the identifiability properties of two im…
Highest Weight Modules Over The Quantum Periplectic Superalgebra of Type
Saber Ahmed, Dimitar Grantcharov, Nicolas Guay
In this paper, we begin the study of highest weight representations of the quantized enveloping superalgebra of type . We introduce a Drinfeld-…
