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…

Schubert defects in Lagrangian Grassmannians
W. Gu, L. Mihalcea, E. Sharpe +3
In this paper, we propose a construction of GLSM defects corresponding to Schubert cycles in Lagrangian Grassmannians, following recent work of Closset-Khlaif on Schubert cycles in…

Quantum K Whitney relations for partial flag varieties
Wei Gu, Leonardo C. Mihalcea, Eric Sharpe +3
In a recent paper, we stated conjectural presentations for the equivariant quantum K ring of partial flag varieties, motivated by physics considerations. In this companion paper, w…
