Equivariant homology of the symplectic affine Grassmannian and dual affine Schur $P$ -functions

Takeshi Ikeda, Shinsuke Iwao, Mark Shimozono

We study the torus-equivariant homology $H_{*}^{T} (Gr_{G})$ of the affine Grassmannian $Gr_{G}$ , where $G = Sp_{2 n} (C)$ is the symplectic group. This homo…

An elementary construction of the ring of dual $K$ - $Q$ -cancellation property

Shinsuke Iwao

This paper presents an elementary introduction on $K$ -theoretic $Q$ -functions, which were introduced by Ikeda and Naruse in 2013. These functions, which serve as $K$ -theoretic anal…
