A characterization of sub-riemannian spaces as length dilatation structures constructed via coherent projections
نویسنده
چکیده
We introduce length dilatation structures on metric spaces, tempered dilatation structures and coherent projections and explore the relations between these objects and the Radon-Nikodym property and Gamma-convergence of length functionals. Then we show that the main properties of sub-riemannian spaces can be obtained from pairs of length dilatation structures, the first being a tempered one and the second obtained via a coherent projection.

Dilatation structures with the Radon-Nikodym property
The notion of a dilatation structure stemmed out from my efforts to understand basic results in sub-Riemannian geometry, especially the last section of the paper by Belläıche [2] and the intrinsic point of view of Gromov [5]. In these papers, as in other articles devoted to sub-Riemannian geometry, fundamental results admiting an intrinsic formulation were proved using differential geometry too...
متن کاملDilatation structures in sub-riemannian geometry
Based on the notion of dilatation structure [2], we give an intrinsic treatment to sub-riemannian geometry, started in the paper [4]. Here we prove that regular sub-riemannian manifolds admit dilatation structures. From the existence of normal frames proved by Belläıche we deduce the rest of the properties of regular sub-riemannian manifolds by using the formalism of dilatation structures.
متن کاملOn the Kirchheim-Magnani counterexample to metric differentiability
In Kirchheim-Magnani [7] the authors construct a left invariant distance ρ on the Heisenberg group such that the identity map id is 1-Lipschitz but it is not metrically differentiable anywhere. In this short note we give an interpretation of the Kirchheim-Magnani counterexample to metric differentiability. In fact we show that they construct something which fails shortly from being a dilatation...
متن کاملLipschitz and Path Isometric Embeddings of Metric Spaces
We prove that each sub-Riemannian manifold can be embedded in some Euclidean space preserving the length of all the curves in the manifold. The result is an extension of Nash C Embedding Theorem. For more general metric spaces the same result is false, e.g., for Finsler non-Riemannian manifolds. However, we also show that any metric space of finite Hausdorff dimension can be embedded in some Eu...
متن کاملTangent bundles to sub-Riemannian groups
1 1 INTRODUCTION 2 1 Introduction Classical calculus is a basic tool in analysis. We use it so often that we forget that its construction needed considerable time and effort. Especially in the last decade, the progresses made in the field of analysis in metric spaces make us reconsider this calculus. Along this line of thought, all started with the definition of Pansu derivative [24] and its ve...
