Cari tutti,

vi segnalo questa attività per il ciclo di seminari dei Baby Geometri:

Lunedì 14 Maggio alle 16:30

presso l'Aula Seminari del Dipartimento di Matematica

Lorenzo Ruffoni (Università di Bologna)

terrà un seminario dal titolo:

Complex projective structures and Hilbert's XXI problem

di cui riporto l'abstract:

Complex projective structures are geometric structures locally modeled on the geometry of the Riemann sphere with its group of Möbius transformations PSL(2,C). As this space appears as a natural boundary at infinity for the hyperbolic space, a typical feature of these structures is the interplay between complex analysis and hyperbolic geometry, which gives rise to a rich deformation theory. After reviewing some of the main properties of their deformation space, we will discuss how the study of complex projective structures can provide solutions to Hilbert's XXI problem about monodromy groups of certain classes of ODEs on Riemann surfaces.

Tutti gli interessati sono invitati a partecipare.
