[Dottorcomp] Seminari di Algebra e Geometria - mercoledì 8 maggio 2024

[Lidia Stoppino]

Il giorno mercoledì 8 maggio 2024
alle 16,30 in aula Beltrami 

Samuel Bronstein (Ecole Normale Supérieure)

terrà un seminario dal titolo: Minimal surfaces and almost Fuchsian representations in the hyperbolic 4-space

Abstract. Developped by Uhlenbeck for the study of Kleinian groups, almost Fuchsian representations are representations of surface group admitting an equivariant minimal disc in the hyperbolic space, whose second fundamental form is small. Such a representation is always discrete and faithful. We generalize this notion to isometries of a negatively curved space, and consider the specific case of the hyperbolic 4-space. We show an example of such representation whose associated complete hyperbolic 4-manifold is a nontrivial disc bundle over the surface.

Tutti gli interessati sono cordialmente invitati a partecipare.
