Heegaard Floer homology and deformation of curve singularities
Vendredi, 17 Février, 2017 - 10:30
Résumé : 

Knots and links naturally appear in the neighbourhood of the singularity of a complex curve; this creates a bridge between algebraic geometry and differential topology. I will discuss a topological approach to the study of 1-parameter families of singular curves, using correction terms in Heegaard Floer homology. This is joint work with József Bodnár and Daniele Celoria.
