[Topology.beta] Tomorrow 11:00 Maryam AG: Nikolas Adaloglou (Leiden)

[Rot, T.O. (Thomas)]

Dear all,

Tomorrow we have an external speaker in the AG. Nikolas Adaloglou(PhD student of Federica Pasquotto) will speak. Title and Abstract below.

As per ususal: 11:00 in Maryam. Hope to see you there!

Best,

Title: What does a Contact Geometer know about Isolated Hypersurface Singularities?

Abstract: Isolated Hypersurface Singularities (IHS) of C^n and their Links have provided topologists with many wonderful and unexpected objects, from Poincare's Homology sphere to Brieskorn's construction of exotic spheres as links of some Fermat singularities. On the other hand, in low dimensions, the topology of the singularity carries a lot of information about its algebraic geometry.

The Link of a singularity is naturally a contact submanifold of S^{2n-1} with the standard contact structure. In this talk, I will try to sketch the symplectic and contact phenomena that appear in the study of Isolated Singularities, going over some key results that motivate current research. Time permitting, I will also mention joint work with F. Pasquotto and A. Zanardini.
