Let $X_l=\widetilde{{\bf C}^2/({\bf Z}/l{\bf Z})}$ be a crepant resolution, let $X_l^{[k]}$ be the Hilbert scheme of $k$ points on $X_l$, and let $\mathcal{M}_{k,d,l}$ denote the s…

Let $X$ be a toric manifold and let ${\bf d}$ be a degree. Jinzenji–Shimizu conjecture. One can construct a compact moduli space of quasi maps from $CP^1$ to $X$ of degree…

Let $\tau:{\mathcal C}_+\to \mathfrak{Q}_{g,m,d,n}^{\delta_+}$ be the universal curve, with universal family of quasi-maps and wall-crossing morphism…
