Title: Approximation and convergence of the first intrinsic volume
Speaker: Herbert Edelsbrunner, Institute of Science and Technology, Austria
Seminar Type: Colloquium
Abstract: The Steiner polynomial of a solid body in R^n is of degree n and describes the volume as a function of the thickening parameter (parallel body). The coefficient of the degree-i term is used to define the (n-i)-th intrinsic volume. Using an integral geometric approach, we modify the Crofton formula using persistent moments to get a measure for approximating bodies that converges to the intrinsic volume of the solid body. We have a proof of convergence for n-i = 1. Work with Florian Pausinger.
