Open Gromov-Witten invariants in dimension six

Abstract

Let $L$ be a closed orientable Lagrangian submanifold of a closed symplectic six-manifold $(X,\omega )$. We assume that the first homology group $H_1(L;A)$ with coefficients in a commutative ring $A$ injects into the group $H_1(X;A)$ and that $X$ contains no Maslov zero pseudo-holomorphic disc with boundary on $L$. Then, we prove that for every generic choice of a tame almost-complex structure $J$ on $X$, every relative homology class $d\in H_2(X,L;\mathbb{Z})$ and adequate number of incidence conditions in $L$ or $X$, the weighted number of $J$-holomorphic discs with boundary on $L$, homologous to $d$, and either irreducible or reducible disconnected, which satisfy the conditions, does not depend on the generic choice of $J$, provided that at least one incidence condition lies in $L$. These numbers thus define open Gromov-Witten invariants in dimension six, taking values in the ring $A$.
