Gromov-Witten invariants of varieties with holomorphic 2-forms

Young-Hoon Kiem, Jun Li

We show that a holomorphic two-form $θ$ on a smooth algebraic variety X localizes the virtual fundamental class of the moduli of stable maps $\mgn(X,β)$ to the locus where $θ$ dege…

Two point extremal Gromov-Witten invariants of Hilbert schemes of points on surfaces

Jun Li, Wei-Ping Li

Given an algebraic surface $X$ , the Hilbert scheme $X^{[n]}$ of $n$ -points on $X$ admits a contraction morphism to the $n$ -fold symmetric product $X^{(n)}$ with the extremal ray ge…
