Abstract: The action and index spectra of a Hamiltonian diffeomorphism
and their behavior
under iterations carry important information about the periodic orbits
of the diffeomorphism. For
instance, on a closed, symplectically aspherical manifold, the
boundedness of the minimal action-
index gap implies the Conley conjecture asserting that such a
diffeomorphism has simple periodic
orbits of arbitrarily large period. In this talk, based on joint works
with Viktor Ginzburg, we will
discuss some results along these lines and, time permitting, touch
upon their proofs.

Tea and coffee will be served at 15:00
