GeomTop Seminar: Triangulating manifolds: An overview with a focus on Riemannian simplices

Date: Wednesday, May 8, 2019 13:00 - 14:15
Speaker: Mathijs Wintraecken
Location: Mondi Seminar Room 3, Central Building
Series: Mathematics and CS Seminar
Host: Herbert Edelsbrunner
Contact: WAGNER Hubert

Defining a simplex on a Riemannian manifold is not straightforward, the convex hull for example is not useful, in all but a few very special cases. In this talk we'll see the construction of Riemannian n-simplices on n-manifolds and conditions for them being homeomorphic to the standard Euclidean n-simplex (which we'll call non-degeneracy conditions). We'll discuss the tools that are used in this definition and non-degeneracy conditions, such as the Toponogov comparison theorem and Riemannian centres of mass.
