Abstract:
In this talk I will review some of basic notion about conformal symplectic geometry and highlight similarities and differences with symplectic geometry. I will then explain how we can prove that in a conformal symplectic cotangent bundle lagrangian intersection of the 0-section with Hamiltonian deformations of itself are bounded bellow by the Novikov Betti numbers of the Lee form. This is joint work with Emmy Murphy.
