On a symmetry of the category of integrable modules (2009)
Cook, William J., Sadowski, Christopher
Haisheng Li showed that given a module (W,Y_W(\cdot,x)) for a vertex algebra (V,Y(\cdot,x)), one can obtain a new V-module W^{\Delta} = (W,Y_W(\Delta(x)\cdot,x)) if \Delta(x) satisfies certain...
Definition 2.1. We define a Tensor Algebra as follows: Let: (2007)
I introduce the notion of a vertex operator algebra, along with some background information on Lie algebras, and give a specific, well known, example of a vertex operator algebra. (This is just some...
