Conference: Symplectic Techniques in Topology and Dynamics 2015

During the week from the 24.08 to the 28.08.2015 I participated at a conference Symplectic Techniques in Topology and Dynamics 2015 at the University of Cologne. The areas the speakers have talked about were widely spread in the field of symplectic geometry starting for example  with the $n$-body problem by Andreas Knauf which is very closely related to application and going to Counterexample by Tolman, which is more on the pure side of math. Over all the whole conference was very inspiring and very good organized. Much thanks for this to Prof. Dr. H. Geiges, Prof. Dr. S. Sabatini and Dr. Kunze. Since I am not an expert in these topics and completely new to the field I could not follow my initial thought of writing a little sum up for every talk. Instead I will just present the titles of all the talkes.

Participating in this conference was very fruitful for me since I realized that this is an area which I want to focus more on! Also I could get in touch with famous persons like Susan Tolman, which are and have been very successful in the area of symplectic geometry.
