Categorical action of the extended braid group of affine type A
Published 28 Apr 2015 in math.GT, math.QA, and math.RT | (1504.07596v1)
Abstract: Using a quiver algebra of a cyclic quiver, we construct a faithful categorical action of the extended braid group of affine type A on its bounded homotopy category of finitely generated projective modules. The algebra is trigraded and we identify the trigraded dimensions of the space of morphisms of this category with intersection numbers coming from the topological origin of the group.
