Namikawa-Weyl groups of affinizations of smooth Nakajima quiver varieties
arXiv:2104.08367
Abstract
We give a description of the Namikawa-Weyl group of affinizations of smooth Nakajima quiver varieties using combinatorial data of the underlying quiver, and compute some explicit examples. This extends a result of McGerty and Nevins for quiver varieties coming from Dynkin quivers.
