Giovedì, 2 Novembre alle ore 14:15, Samuel Grushevsky (Stony Brook University) terrà il seminario di Geometria dal titolo "Ends of strata of differentials".
Abstract: The moduli spaces of complex curves together with a meromorphic differential with prescribed multiplicities of zeros and poles are the phase spaces of the action of GL(2,R) in Teichmuller dynamics, and are natural interesting geometric subvarieties of the moduli of curves with marked points. The geometry and topology of the strata remain mysterious, and we will present perhaps the first topological result beyond the number of connected components: that every connected component of every stratum in genus at least 2 has only one end; equivalently, this says that the boundary of a smooth compactification is connected. Based on joint work with Ben Dozier
Il seminario si svolgerà in presenza nell'aula M1. Per ulteriori informazioni, e per il link Teams per seguire il seminario a distanza, si può contattare gli organizzatori all'email firstname.lastname@example.org.
