Resumen de A new Weyl group action related to the quasi-classical Gelfand–Graev action

• 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.
