Summary Report
Eight main talks were distributed during the workshop, followed by discussion sessions.
During the discussions, we identified the following question. Hind-Mikhalkin-Schlenk have shown that a monotone Markov Lagrangian torus in the projective plane has precisely three symplectic spheres in its complement up to Hamiltonian isotopy. In the same time, non-monotone tori can have more than 3 symplectic spheres in their complement. This turns our attention to the wall-crossing formula for the homology classes of the three spheres. There are applications to the understanding of the Hamiltonian isotopy class of a torus after inflating some given symplectic sphere in its complement.
