Changjian Su: Equivariant K-theory realization of the affine i-quantum group #ICBS2024

By the construction of Ginzburg and Vasserot, the equivariant K-theory of the generalized Steinberg variety of type A realizes the corresponding affine quantum group. We will talk about a type C generalization of this construction, the corresponding algebra becomes the affine i-quantum group of type AIII. We can use this to construct some simple/standard modules of the i-quantum group. This is based on a joint work in progress with Weiqiang Wang.
