A new Weyl group action related to the quasi-classical Gelfand-Graev action
Published 10 Dec 2019 in math.RT, math.AG, and math.SG | (1912.04539v3)
Abstract: We construct a Weyl group action on the DKS type varieties, a certain class of varieties associated with quivers. As a result, on some special DKS type varieties, we can give a quiver theoretic explanation of the quasi-classical Gelfand-Graev action discovered by Ginzburg and Riche and studied by Ginzburg and Kazhdan recently.
