François Charette: Quantum Reidemeister torsion and open Gromov-Witten invariants

I will recall the notion of torsion of an acyclic chain complex.  This can then be applied to the pearl complex when a Lagrangian has no self-Floer homology, which happens almost all the time (I will say why) when using local systems.  This new invariant can be expressed as a rational function of certain open Gromov-Witten invariants.  Finally, I will discuss applications to the monotone Lagrangian 3-manifolds
