Extremal Gromov-Witten invariants of the Hilbert scheme of 3 Points
Forum of Mathematics, Sigma(2023)
Abstract
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 Gromov-Witten invariant of the Hilbert scheme of n points with n being arbitrary. The main ideas in the proofs are to use geometric arguments involving the cosection localization theory of Kiem and J. Li [17, 23], algebraic manipulations related to the Heisenberg operators of Grojnowski [13] and Nakajima [34], and the virtual localization formulas of Gromov-Witten theory [12, 20, 30].
