DESCRIPTION:Abstract: Defining a simplex on a Riemannian manifold is not st
 raightforward\, the convex hull for example is not useful\, in all but a f
 ew very special cases. In this talk we'll see the construction of Riemanni
 an n-simplices on n-manifolds and conditions for them being homeomorphic t
 o the standard Euclidean n-simplex (which we'll call non-degeneracy condit
 ions). We'll discuss the tools that are used in this definition and non-de
 generacy conditions\, such as the Toponogov comparison theorem and Riemann
 ian centres of mass.
