Orthogonal webs and semisimplification
arXiv:2401.00704 · doi:10.5070/C65365560
Abstract
We define a diagrammatic category that is equivalent to tilting representations for the orthogonal group. Our construction works in characteristic not equal to two. We also describe the semisimplification of this category.
