Let $N\geq 2$. Consider the quantized Coulomb branch of the four-dimensional $\mathcal{N}=2$ $Sp(N)$ gauge theory with four hypermultiplets in the fundamental representation and on…

Let $Q$ be a quiver, let $\mathbb{P}^1$ be the projective line, and let $X$ be a quiver variety of type $Q$. Consider the moduli space of quasimaps from $\mathbb{P}^1$ to $X$ and i…

Let $\mathfrak{M}_{\mathbb{Q}}$ be the commutative resolution associated with the Coulomb branch, let $\pi$ be the relevant fundamental group acting on…

Let $\phi$ be a parameter for the quantized Coulomb branch, and call it generic when it lies outside the exceptional hyperplanes governing the chamber decomposition. Let…
