Point-like bounding chains in open Gromov-Witten theory
Over a decade ago, Welschinger defined real enumerative invariants in dimensions 2 and 3. It has remained an open problem to extend these invariants to higher dimensions. I will discuss a solution to this problem in the language of open Gromov-Witten theory. The key idea is that boundary point constraints should be replaced with canonical gauge equivalence classes of Maurer-Cartan elements (bounding chains) in the relevant Fukaya A-infinity algebra. The resulting invariants satisfy a version of the open WDVV equation, which determines all invariants for projective spaces. Conjugation symmetry does not place an essential role in our arguments.
