(Un)distorted diffeomorphisms in different regularities

چکیده
We build the first examples of diffeomorphisms that are distorted in a group C1 yet undistorted corresponding C2 diffeomorphisms. This explicit construction is performed for closed interval.

Undistorted Solvable Linear Groups
We discuss distortion of solvable linear groups over a locally compact field and provide necessary and sufficient conditions for a subgroup to be undistorted when the field is of characteristic zero.
متن کاملPotassium Channels: Complete and Undistorted
The recently determined structure of a mammalian voltage-gated potassium channel has important implications for our understanding of voltage-sensing and gating mechanisms in channels. It is also the first crystal structure of an overexpressed eukaryotic membrane protein.
متن کاملUndistorted Lensed Images in Galaxy Clusters
To date, the study of high-magniication gravitational lensing eeects of galaxy clusters has focused upon the grossly distorted, luminous arc-like features formed in massive, centrally condensed clusters. We investigate the formation of a diierent type of image , highly magniied yet undistorted, in two widely employed cluster mass density prooles; an isothermal sphere with a core, and a universa...
متن کاملUndistorted Projection onto Dynamic Surface
For projector-based augmented reality systems, geometric correction is a crucial function. There have been many researches on the geometric correction in the literature. However, most of them focused only on static projection surfaces and could not give us a solution for dynamic surfaces (with varying geometry in time). In this paper, we aim at providing a simple and robust framework for projec...
متن کاملExamples of Different Minimal Diffeomorphisms Giving the Same C*-algebras
We give examples of minimal diffeomorphisms of compact connected manifolds which are not topologically orbit equivalent, but whose transformation group C*-algebras are isomorphic. The examples show that the following properties of a minimal diffeomorphism are not invariants of the transformation group C*-algebra: having topologically quasidiscrete spectrum; the action on singular cohomology (wh...
