"The Arnold conjecture and Hamiltonian homeomorphisms"

The Arnold conjecture on fixed points of Hamiltonian diffeomorphisms has been one of the main driving forces in the development of symplectic topology.  After presenting the conjecture, we will introduce the notion of Hamiltonian homeomorphisms and will discuss whether the conjecture holds in non-smooth settings.  The talk will be accessible to a broad audience.
