Abstract
In the framework of equivariant quantum K-theory of Nakajima quiver varieties we construct a q-analog of a Frobenius intertwiner between $\mathbb{Z}/p\mathbb{Z}$-equivariant quantum K-theory and the standard conventional quantum K-theory. We prove that this operator has no poles at primitive complex $p$-th roots of unity in the curve counting parameter $q$. As a byproduct, we show that the eigenvalues of the iterated product of quantum difference operators by quantum bundles $\mathcal{L}$ of quiver variety $X$
evaluated at roots of unity are governed by Bethe equations for $X$ with all variables substituted by their $p$-th powers. In the cohomological limit, the above iterated product is conjectured to reduce to the p-curvature of the quantum connection for prime $p$.

Speaker Intro
My education begain in Russia where I learned math and physics at Moscow Insitute of Physics and Technology. I started my research career as a theoretical physicist after obtaining my PhD from University of Minnesota in 2012. At first, my research focus was drawn to various aspects of supersymmetric gauge theories and string theory. However, I have always been drawn to pure abstract mathematics since my student days. Since around 2017 I have been a full time mathematician.
My current research is focused on the interaction between enumerative algebraic geometry, geometric representation theory and integrable systems. In general I work on physical mathematics which nowadays represents a large part of modern math. A significant amount of problems that are studied by mathematicians comes from string/gauge theory. More recently I began to study number theory and how it is connected to other branches of mathematics.
