SEMINARI DI GEOMETRIA

Titolo: PLANE CUSPIDAL CURVES AND HEEGAARD FLOER HOMOLOGY Tuesday, November 18, 2014 Ora: 14:00 Aula: Sala Seminari (Dip. Matematica) Relatore: Marco Golla (Unversità di Pisa)

Abstract: In this talk, I will focus on applications of Heegaard Floer homology to the study of genus-g plane curves in CP^2, with one cuspidal singularity: I will discuss bounds on the semigroup counting function of the singularity and show their effectiveness; I will also show examples of families of "simple" singular curves for infinitely many genera. This is joint work with József Bodnar and Daniele Celoria.
