A Simple Proof of an Estimate for the Approximation of the Euclidean Ball and the Delone Triangulation Numbers Original Research Article

We give a simple proof of an estimate for the approximation of the Euclidean ball by a polytope with a given number of vertices with respect to the volume of the symmetric difference metric and relatively precise estimate for the Delone triangulation numbers. We also study the same problem for a given number of n−1-dimensional faces.
