Cari tutti,

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

Lunedì 7 Maggio alle 16:30

presso l'Aula Seminari del Dipartimento di Matematica

Gianluca Faraco (Università degli Studi di Parma)

terrà un seminario dal titolo:

Be hyperbolic! Be pure!

di cui riporto l'abstract:

In this talk we will talk about the relationship between hyperbolic
cone-structures and their holonomy representations. Any hyperbolic
structure on a given closed compact and orientable surface S induces in a
very natural way a representation of the fundamental group in the Lie
group PSL(2,R), which encodes geometric data about the structure. The
reverse problem to recover a hyperbolic cone-structure from a given
representation is more arduous and longer. Even worse it is not always
possible. In the first part of this talk we will consider this problem
from a general viewpoint giving examples of representations that not arise
as the holonomy of hyperbolic cone-structure. In the second part we focus
our attention to a very special class of representations, namely purely
hyperbolic representations.



Tutti gli interessati sono invitati a partecipare.
