Diagrammatic singular Soergel bimodules

Abstract: In joint work with Ben Elias, Nicolas Libedinsky, Leonardo Patimo, we construct a diagrammatic basis of the morphism spaces of singular Soergel bimodules, analogous to the diagrammatic basis for the regular Soergel bimodules given by Elias-Williamson (modelled on the algebraic `light leaves' basis due to Libedinsky). The talk is an introduction to this diagrammatics and related combinatorics, where we also aim to draw some singular light leaves.
