quasi-isometric embedding theorem groups Group Theory
2012/3/1
We show that every group $H$ of at most exponential growth with respect to some left invariant metric admits a bi-Lipschitz embedding into a finitely generated group $G$ such that $G$ is amenable (res...
Quasi-Isometric and Quasi-Conformal Development of Triangulated Surfaces for Computerized Tomography
Quasi-Isometric Quasi-Conformal Triangulated Surfaces
2010/1/7
In this paper we present a simple method for minimal distortion development of triangulated surfaces for mapping and imaging. The method is based on classical results of F. Gehring and Y. V¨ais¨al¨a r...
