We determine all the extremal Gromov-Witten invariants of the Hilbert scheme of $3$ points on a smooth projective complex surface. Our result for the genus- $1$ case verifies a conjecture that we propose for the genus- $1$ extremal Gro

We established a relation between elliptic Gromov-Witten invariants of a symplectic manifold M and its blowups along smooth curves and surfaces.

Let $$\mathsf {X}$$ be a compact symplectic orbifold groupoid with $$\mathsf {S}$$ being a compact symplectic sub-orbifold groupoid, and $${\underline{\mathsf {X}}_{\mathfrak {a}}}$$ be the weight- $${\mathfrak {a}}$$ blowup of $$\mathsf {X}$$ along

We prove that the Hilbert schemes of 2-points on rational surfaces are numerically rationally connected. The main idea is to show that certain 3-point genus-0 Gromov–Witten invariant of the Hilbert scheme of two points on the complex projective pla

Electrically-assisted manufacturing refers to the direct application of electrical current to a workpiece during a manufacturing process. This assistance results in several benefits such as flow stress reduction, increased elongation, reduced springb

Using the degeneration formula and absolute/relative correspondence, we study the change of Gromov–Witten invariants under blow-ups for smooth projective threefolds, and obtain several closed blow-up formulae for high genus Gromov–Witten invarian

Gamma conjecture I and the underlying Conjecture $\mathcal{O}$ for Fano manifolds were proposed by Galkin, Golyshev and Iritani recently. We show that both conjectures hold for all two-dimensional Fano manifolds. We prove Conjecture $\mathcal{O}$ by

Using the degeneration formula for Doanldson-Thomas in- variants, we proved a formula for the change of Donaldson-Thomas in- variants of local surfaces under blowing up along points. Given a smooth projective Calabi-Yau 3-fold X, the moduli space of
