Periodic orbits in cotangent bundles of non-compact manifolds
Monday, 2.6.14, 16:15-17:15, Raum 404, Eckerstr. 1
In this talk I will discuss some existence results for periodic orbits on fixed\nenergy levels of mechanical Hamiltonian systems. In particular, these\nenergy hypersurfaces are allowed to be non-compact.\nI will focus on the analytical and geometrical problems posed by the lack of \ncompactness and discuss advantages and limitations of our method of proof \n("linking"). This is joint work with T. Rot, J.B. van den Berg and R. Vandervorst.

Algebraic cycles of abelian schemes
Friday, 13.6.14, 10:15-11:15, Raum 125, Eckerstr. 1
Let X be a variety and consider the cycle class map, which maps the Chow groups of X to the cohomology groups of X. Hodge or Tate conjectures predict what should be the image of such a map, and Bloch-Beilinson-Murre conjecture predicts some structures on the kernel. We will investigate these conjectures when X is an abelian scheme, and especially when it is the universal abelian scheme over a PEL Shimura variety

Applications of Morse theory to cuplength estimates in symplectic geometry
Monday, 30.6.14, 16:15-17:15, Raum 404, Eckerstr. 1
There are many estimates in symplectic geometry which provide a lower bound for the number of, e.g., periodic orbits of Hamiltonian systems or Hamiltonian chords of Lagrangian submanifolds.\nIn this talk, I will describe various Floer theories related to these estimates and sketch a Morse theoretic argument which can be applied to the Floer settings to give a unifoed proof of these estimates. Moreover, this argument is also applicable in other cases, where the corresponding cuplength estimates was not known before.
