On the Quantum K-theory of Quiver Varieties at Roots of Unity
Let $\Psi(\mathbb{z},\mathbb{a},q)$ be the fundamental solution matrix of the quantum difference equation in the equivariant quantum K-theory for Nakajima variety $X$. In this work, we prove that the operator $$ \Psi(\mathbb{z},\mathbb{a},q) \Psi\left(\mathbb{z}^p,\mathbb{a}^p,q^{p^2}\right)^{-1} $$ has no poles at the primitive complex $p$-th roots of unity $\zeta_p$ in the curve counting parameter …
