TRINO ALGEBRAIC GEOMETRY SEMINARS 2023

Dear All,

This is to announce the next appointment with the TRINO 
<https://sites.google.com/view/trinotriestino/home>Algebraic Geometry 
Seminar.

Time and Venue: Tuesday May 30 at 15:00, University of Trieste, H2bis 
building in via Valerio 12/1, Aula Seminari, third floor.

Speaker: Marc Kegel (Humbold-Universität zu Berlin)

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.


All interested are welcome to attend!

All the best,


Yulieth Prieto

On behalf of the Trino organizers
