On 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 کاملMetric Derived Numbers and Continuous Metric Differentiability via Homeomorphisms
We define the notions of unilateral metric derivatives and “metric derived numbers” in analogy with Dini derivatives (also referred to as “derived numbers”) and establish their basic properties. We also prove that the set of points where a path with values in a metric space with continuous metric derivative is not “metrically differentiable” (in a certain strong sense) is σsymmetrically porous ...
متن کاملInfinitesimal Structure of Differentiability Spaces, and Metric Differentiation
We prove metric differentiation for differentiability spaces in the sense of Cheeger [Che99, Kei04a, Bat12]. As corollaries we give a new proof of one of the main results of [Che99], a proof that the Lip-lip constant of any Liplip space in the sense of Keith [Kei04a] is equal to 1, and new nonembeddability results.
متن کاملDifferentiability Properties of Metric Projections onto Convex Sets
It is known that directional differentiability of metric projection onto a closed convex set in a finite dimensional space is not guaranteed. In this paper we discuss sufficient conditions ensuring directional differentiability of such metric projections. The approach is based on a general theory of sensitivity analysis of parameterized optimization problems.
متن کاملDIFFERENTIABILITY OF p-HARMONIC FUNCTIONS ON METRIC MEASURE SPACES
We study p-harmonic functions on metric measure spaces, which are formulated as minimizers to certain energy functionals. For spaces supporting a p-Poincaré inequality, we show that such functions satisfy an infinitesmal Lipschitz condition almost everywhere. This result is essentially sharp, since there are examples of metric spaces and p-harmonic functions that fail to be locally Lipschitz co...
