On the -theoretic logarithmic double ramification class
Kamyar Amini, You-Cheng Chou, Leo Herr +3
The paper defines a K‑theoretic version of the logarithmic double ramification class, proves a product formula and GLₙ(ℤ)‑invariance, and provides an explicit expression using Grot…

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 . The proof relies on pushing forward the Toda…

Lifting -functions from the Grassmannians to their cotangent bundles
Kamyar Amini
We relate two fundamental enumerative functions, namely the -functions in the quantum -ring of and of its cotangent bundle, by defining a -theoretic operator on c…
