A bridge from surface singularities to contact 3-manifolds


Speaker: Burak Ozbagci, MSRI

We will explain the relation between the topology of surface singularities and three dimensional contact manifolds via so called Milnor open books. We will give an example to prove that Milnor open books do not necessarily minimize the genus among open books which support the canonical contact structures on the links of the surface singularities. This is joint work with Mohan Bhupal
