UniTS Geometry seminar - 30 May / Reminder

[ZUDDAS DANIELE]

Dear colleagues,

it is my pleasure to announce a talk by Marc Kegel (Humboldt-Universität zu Berlin) that will be held on May 30.

There will be a social dinner on the same day at 20:00 at Marinato (Riva Nazario Sauro 4).

Title: Khovanov homology of positive links and of L-space knots

Abstract: A knot is called positive if it admits a diagram with only positive crossings. We will discuss that such knots enjoy many interesting properties and are closely related to other fields, such as algebraic geometry, symplectic and contact topology, gauge theory, and smooth 4-manifold topology. Then we will introduce a new obstruction for positivity of knots in terms of Khovanov homology. This is based on joint work with Naageswaran Manikandan, Leo Mousseau, and Marithania Silvero.

Date: 30 May at 15:00
Venue: Sala Seminari, III floor of H2bis building, University of Trieste, Via Valerio 12/1.

As Marc told me, the talk will be accessible to everyone with basic knowledge of geometry and topology (and in particular to Ph.D. students).

If you would like to join the dinner please let me know by email as soon as possible.
