Maffei's action and symplectic Springer action for quiver varieties
Yaochen Wu
We examine the relationship between the actions of two Weyl groups on the cohomology of a smooth quiver variety: the Maffei's action of the Weyl group associated to the quiver, and…

Harish-Chandra bimodules over quantized flower quiver varieties with minimal support
Yaochen Wu
We classify Harish-Chandra bimodules over the quantized flower quiver varieties with minimal support. We show that if the dimension vector is , then there are minimally sup…

Namikawa-Weyl groups of affinizations of smooth Nakajima quiver varieties
Yaochen Wu
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 e…
