%0 Journal Article %T Intersection theoretic properties on the moduli space of genus 0 stable maps to a semipositive symplectic 4-manifold %A Seongchun Kwon %J Mathematics %D 2005 %I arXiv %X We characterize transversality, non-transversality properties on the moduli space of genus 0 stable maps to a semipositive symplectic manifold of dimension 4, when GW([point],...,[point]) is enumerative. In particular, we show that the intersection theoretic property depends on the existence of a critical point on a stable map. %U http://arxiv.org/abs/math/0502297v3
