Cari colleghi,

vi segnalo il prossimo seminario di geometria, giovedì 29 gennaio alle 14:30 in aula Riunioni. Trovate qui sotto titolo e abstract.

Vi esorterei, inoltre, a indicarmi nomi di persone che vorreste invitare in questi prossimi mesi per tenere seminari, in quanto abbiamo parecchi fondi per farlo.

Saluti,

Andrea

Titolo: Volumes of maximal representations into SO(2,3)

Speaker: Timothe Lemistre (Nice)

Abstract: Maximal representations of a surface group into a hermitian Lie group G form connected components of the character variety generalising the Teichmüller space. When G=SO(2,3), those representations act cocompactly on some convex domain in the pseudo-hyperbolic space (a pseudo-riemannian analogue of the hyperbolic space), and one can define a volume functional on the space of maximal representations. In this talk I will explain a surprising result concerning the boundedness of this volume functional.
