VII Workshop on Differential Geometry 

20-24 March 2017, Maceió-Brazil


The Workshop on Differential Geometry of the Institute of Mathematics of the Federal University of Alagoas has become a traditional event that takes place every year in Maceio-Alagoas, during the Brazilian summer. The aim of this workshop is to gather in Maceio national and international researchers of high scientific level in the field of differential geometry.

Title: Horospherical rigidity of closed negatively curved manifold

Abstract: This is a joint work with Gilles Courtois and Sa'ar Hersonsky. The goal is to understand the proof of the theorem that assets that a closed negatively curved manifold which has one flat horosphere has constant curvature. The proof relies on an interplay between Geometry and Dynamical systems and this will be the opportunity to describe both of them for negative curvature. We will also place this research in a wider context.
