WebOct 18, 2012 · We show that isometries between open sets of Carnot groups are affine. This result generalizes a result of Hamenstadt. Our proof does not rely on her proof. In addition, we study global isometries of general homogeneous manifolds equipped with left-invariant subFinsler distances. We show that each isometry is determined by the blow up … WebDensitometer definition, an instrument for measuring the density of negatives. See more.

WebMar 20, 2024 · Clearly, not all isometries are local. A general isometry would act nontrivially on the full space rather than only on $\mathcal H_A$ or $\mathcal H_B$. For example, a unitary such as the QFT matrix on the pair of qubits is a nonlocal isometry. WebUrsula Hamenstadt¨ 1 Teichmu¨ller Theory 3 Introduction 3 Lecture 1. Hyperbolic Surfaces 5 Lecture 2.

Isometries of Carnot groups and subFinsler homogeneous manifolds

WebHamenstadt's results that, assuming that all geodesies are normal, isometries are smooth [Ham90, Theorem 6.2]. If the underlying structure is a Carnot group (see Example 2.4), then by virtue of the work of Hamenstadt and of Kishimoto [Ham90, Corollary 8.4], [Kis03, Theorem 4.2], one has a stronger result: Global isometries Web(1) G does not act properly on any proper CAT(0) space of dimension 2 by isometries. (2) G acts properly and co-compactly on some proper CAT(0) space of di-mension 3 by isometries. In particular, G is a CAT(0) group.
