über das Thema:
|Starting from a contact structure on an odd-dimensional manifold M together with a supporting open book, Bourgeois '02 gave an explicit recipe to build a contact structure on the product of M with the 2-torus T. After giving an introduction to this construction and explaining the motivations behind the study of its properties, I will sketch a proof of the following result, which is joint work with Jonathan Bowden and Agustin Moreno: if the original manifold M is 3-dimensional, then the Bourgeois construction always results in a tight contact structure on M x T, independently of the tightness/overtwistedness of the contact structure on M and of the chosen supporting open book.|
