Categorification of the internal braid group action for quantum groups I: 2-functoriality

Michael T. Abram, Laffite Lamberto-Egan, Aaron D. Lauda +1

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.
