Subdivision and runner removal theorems
Abstract
We develop a combinatorial framework for the subdivision map -- introduced by Maksimau, Mathas and Tubbenhauer -- between the KLR(W) algebras of type $A^{(1)}_{e-1}$ and type $A^{(1)}_{e}$, which provides a partial categorification of the runner removal theorems.
