Seidel product formula in equivariant quantum $K$ -theory of flag varieties

Takeshi Ikeda, Takafumi Kouno, Satoshi Naito

We prove a Seidel product formula for the torus-equivariant quantum $K$ -theory of a generalized flag variety $G / P .$ This is a natural generalization of the corresponding results by…

Quantum $K$ -theory of Lagrangian Grassmannian via parabolic Peterson isomorphism

Takeshi Ikeda, Takafumi Kouno, Yusuke Nakayama +1

We study Schubert calculus in the torus-equivariant quantum $K$ -ring of the Lagrangian Grassmannian $LG (n)$ . Our main tool is the $K$ -theoretic Peterson map due to Kato. T…
