This leads us to a degeneration axiom and a gluing axiom for open Gromov-Witten invariants. They provide then a route to the construction of virtual fundamental chains via specialization. Comments on the equivalence of the degeneration formula of closed Gromov-Witten invariants by Li-Ruan/Li versus Ionel-Parker are given in the Appendix.102+2 pagesSymplectic GeometryHigh Energy Physics - TheoryAlgebraic Geometry53D45; 14N35, 81T30text
