Billey-Type Formula for KL-Schubert Classes in Hyperbolic Cohomology
Cristian Lenart, Krista Zehr, Changlong Zhong
This paper studies the KL-Schubert classes defined by Kazhdan-Lusztig bases in -theory and hyperbolic cohomology of flag varieties. We first establish Poincaré dualities of the…

Quantum -theoretic divisor axiom for flag manifolds
Cristian Lenart, Satoshi Naito, Daisuke Sagaki +2
We prove an identity for (torus-equivariant) 3-point, genus 0, -theoretic Gromov-Witten invariants of flag manifolds , which can be thought of as a replacement for the ``di…

Combinatorial Aspects of Elliptic Schubert Calculus
Cristian Lenart, Rui Xiong, Changlong Zhong
The main goal of this paper is to extend two fundamental combinatorial results in Schubert calculus on flag manifolds from equivariant cohomology and -theory to equivariant elli…
