## Klaus Niederkrüger (Toulouse):Topology of symplectic fillings

ABSTRACTS:
Contact manifolds often occur naturally as boundaries of complex or
symplectic manifolds. An interesting question is in how far a given
contact manifold might appear as boundary of several different
symplectic manifolds, and if there are restrictions on the topology of
the possible symplectic "fillings". In this talk, I will explain how
Gromov's pseudo-holomorphic curve techniques allow us to prove some (old
and new) results in this direction.
