Higher genus symplectic invariants and sigma model coupled with gravity

arXiv:alg-geom/9601005 · doi:10.1007/s002220050192

Abstract

We define higher genus Gromov-Witten invariants and establish a mathematical theory of sigma model coupled with gravity over any semi-positive symplectic manifolds. As applications, we verify the stablizing conjecture of symplectic 4-manifolds for simply connected elliptic surfaces and construct smooth 6-manifolds admitting infinitely many deformation classes of symplectic structures.
