Open Gromov-Witten theory for cohomologically incompressible Lagrangians

Abstract: This paper classifies separated bounding pairs for Lagrangian submanifolds that are homologically trivial inside the ambient space, under the assumption that restriction on cohomology from the ambient space to the Lagrangian is surjective. As an application, open Gromov-Witten invariants are defined under the above assumptions. When the Lagrangian is the fixed locus of an anti-symplectic involution, the surjectivity assumption can be somewhat relaxed while the classifying space needs to be modified.
