A diagrammatic approach to reflection functors
For an arbitrary symmetrizable generalized Cartan matrix, the category of modules over the quiver Hecke algebra provides a categorification of the associated quantum group. In this talk, I will present a detailed construction of reflection functors that categorify Lusztig’s braid group action, from the viewpoint of higher representation theory. Similar functors have recently been constructed independently by Kashiwara-Kim-Oh-Park.
