Approximate Differentiability of Mappings of Carnot-Carathéodory Spaces
Sergey Basalaev, Sergey Vodopyanov
We study the approximate differentiability of measurable mappings of Carnot--Carathéodory spaces. We show that the approximate differentiability almost everywhere is equivalent to…

Sharp geometric rigidity of isometries on Heisenberg groups
D. V. Isangulova, S. K. Vodopyanov
We prove sharp geometric rigidity estimates for isometries on Heisenberg groups. Our main result asserts that every -quasi-isometry on a John domain of the Heisenb…
