Categorification of the internal braid group action for quantum groups I: 2-functoriality
arXiv:2205.04598 · doi:10.2140/pjm.2024.328.1
Abstract
We define 2-functors on the categorified quantum group of a simply-laced Kac-Moody algebra that induce Lusztig's internal braid group action at the level of the Grothendieck group.
