The Decomposition Problem for bi-Lipschitz maps of spheres
The Decomposition Problem for bi-Lipschitz maps of spheres
Let denote the orientation-preserving homeomorphisms of the -sphere that are bi-Lipschitz. For a bi-Lipschitz map, its isometric distortion is the least such that the map is -bi-Lipschitz. Decomposition Problem. Let and let . Then for every there are an integer and homeomorphisms , for , such that
with each having isometric distortion at most . The problem asks whether every bi-Lipschitz map of a sphere admits such a finite decomposition into maps with arbitrarily small distortion; the supplied context does not establish whether the assertion is known in full generality.
