Vertex operators for imaginary subalgebras in the Monster Lie Algebra
Darlayne Addabbo, Lisa Carbone, Elizabeth Jurisich +2
The Monster Lie algebra is a quotient of the physical space of the vertex algebra , where is the Moonshine module vertex ope…
Difference Hierarchies for -Functions
Darlayne Addabbo, Maarten Bergvelt
We introduce hierarchies of difference equations (referred to as -systems) associated to the action of a (centrally extended, completed) infinite matrix group $GL_{\infty}^{(n)…
-Functions, Birkhoff Factorizations and Difference Equations
Darlayne Addabbo, Maarten Bergvelt
-systems and -systems are systems of integrable difference equations that have recently attracted much attention, and have wide applications in representation theory and stat…
Generalizations of -systems and Orthogonal Polynomials from Representation Theory
Darlayne Addabbo, Maarten Bergvelt
We briefly describe what tau-functions in integrable systems are. We then define a collection of tau-functions given as matrix elements for the action of on two-co…
