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.
