Virtual Structure Constants as Intersection Numbers of Moduli Space of Polynomial Maps with Two Marked Points
Abstract
In this paper, we derive the virtual structure constants used in mirror computation of degree k hypersurface in CPN-1, by using localization computation applied to moduli space of polynomial maps from CP1 to CPN-1 with two marked points. We also apply this technique to non-nef local geometry O(1)+O(-3)->CP1 and realize mirror computation without using Birkhoff factorization.
