Quantum $K$ -theoretic divisor axiom for flag manifolds

Cristian Lenart, Satoshi Naito, Daisuke Sagaki +2

We prove an identity for (torus-equivariant) 3-point, genus 0, $K$ -theoretic Gromov-Witten invariants of flag manifolds $G / P$ , which can be thought of as a replacement for the ``di…

Toda-Type Presentations for the Quantum K Theory of Partial Flag Varieties

Kamyar Amini, Irit Huq-Kuruvilla, Leonardo C. Mihalcea +2

We prove a determinantal, Toda-type, presentation for the equivariant K theory of a partial flag variety $Fl (r_{1}, \dots, r_{k}; n)$ . The proof relies on pushing forward the Toda…

K-theoretic Gromov-Witten invariants of line degrees on flag varieties

Anders S. Buch, Linda Chen, Weihong Xu

A homology class $d \in H_{2} (X)$ of a complex flag variety $X = G / P$ is called a line degree if the moduli space $M_{0, 0} (X, d)$ of 0-pointed stable maps to $X$ of degree…
