In this talk, I will discuss work in progress, joint with Kai Hugtenburg, on defining open Gromov-Witten invariants (in genus zero) for embedded relatively spin Lagrangians in general closed symplectic manifolds. Our definition rests on the construction of a global Kuranishi chart for the relevant moduli spaces and is an invariant of the almost complex structure. We prove a relation between the invariants of Lagrangians related a Lagrangian cobordism. Time permitting, I will also discuss some results in higher genus.
