Abstract:
In this paper we bound the difference between the total mean curvatures of two closed surfaces in in terms of their total absolute curvatures and the Frechet distance between the volumes they enclose. The proof relies on a combination of methods from algebraic topology and integral geometry. We also bound the difference between the lengths of two curves using the same methods.
