Matrix recursion for positive characteristic diagrammatic Soergel bimodules for affine Weyl groups

Amit Hazi

Let $W$ be an affine Weyl group, and let $\mathbb{k}$ be a field of characteristic $p>0$. The diagrammatic Hecke category $\mathcal{D}$ for $W$ over $\mathbb{k}$ is a categorification of the…
