The diagrammatic category of Soergel bimodules is an additive monoidal category over a field with a diagrammatic presentation. It provides a useful replacement for the category of Soergel bimodules over fields of positive characteristic. Determining the indecomposables in this category is a difficult problem, with connections to Kazhdan-Lusztig theory and modular representation theory of reductive algebraic groups. In this talk I will describe what I call a “linkage principle” for such categories over an affine Weyl group.
