Title: Global perturbations with symmetry

Abstract: The search for existence of leafwise intersection points is motivated by the question if it is possible that a Hamiltonian system survives a global perturbation unharmed. In a joint work with Peter Albers we examined a system which in general does not need to have leafwise intersection points, nevertheless admits infinitely many leafwise intersection points if the perturbation is invariant under a symmetry. This result is obtained by comparing Rabinowitz Floer homology with an equivariant version of it.
