On the Schubert calculus of the quantum K-theory for partial flag manifolds: a 3d A-model perspective
Zhihao Duan, Osama Khlaif, Hao Zou
We further investigate the 3d gauged linear sigma model (GLSM)/~quantum K-theory correspondence for partial flag manifolds . This is a 3d uplif…
Schubert line defects in 3d GLSMs, part I: Complete flag manifolds and quantum Grothendieck polynomials
Cyril Closset, Wei Gu, Osama Khlaif +3
We construct new half-BPS line defects in 3d supersymmetric quiver gauge theories whose Higgs branches are complete flag manifolds . Upon circle co…
Schubert line defects in 3d GLSMs, part II: Partial flag manifolds and parabolic quantum polynomials
Cyril Closset, Wei Gu, Osama Khlaif +3
We construct Schubert line defects in the 3d supersymmetric gauged linear sigma model (GLSM) with target space a partial flag manifold $X={\rm Fl}({\boldsymbol{k}};…
A GLSM realization of derived equivalence in models
Jirui Guo, Ban Lin, Hao Zou
This paper studies the derived equivalence between Calabi--Yau mixed branches using the B-brane hemisphere partition function in anomalous gauged linear sigma models (GLSMs). For a…
A Nakayama result for the quantum K theory of homogeneous spaces
Wei Gu, Leonardo C. Mihalcea, Eric Sharpe +3
We prove that the ideal of relations in the (equivariant) quantum K ring of a homogeneous space is generated by quantizations of each of the generators of the ideal in the classica…
Notes on GLSMs for Supermanifolds and Their Mirrors
Hao Zou
In this paper, we revisit the A-twisted gauged linear sigma models (GLSMs) whose geometric phases are complex Kähler supermanifolds. For abelian models without superpotentials we…
