Project description

One goal is to find a solution to the following problem by J. Moser: Find conditions under which a given Hamiltonian diffeomorphism of a symplectic manifold has a leafwise fixed point. Such points generalize fixed points and Lagrangian intersection points. They also arise in the context of time-dependent perturbations of classical mechanical systems. The existence of such points has applications e.g. to the presymplectic embedding problem and the existence of stably exotic symplectic forms.

I suggest to attack Moser's problem by defining a Floer homology for a coisotropic submanifold. I am open for suggestions about alternative approaches or alternative problems.
