Finer Geometric Rigidity of Limit Sets of Conformal Ifs
نویسنده
چکیده
We consider infinite conformal iterated function systems in the phase space Rd with d ≥ 3. Let J be the limit set of such a system. Under a mild technical assumption, which is always satisfied if the system is finite, we prove that either the Hausdorff dimension of J exceeds the topological dimension k of the closure of J or else the closure of J is a proper compact subset of either a geometric sphere or an affine subspace of dimension k. A similar dichotomy holds for conformal expanding repellers.

Finer Diophantine and Regularity Properties of 1-dimensional Parabolic Ifs
Recall that a Borel probability measure μ on IR is called extremal if μ-almost every number in IR is not very well approximable. In this paper, we prove extremality (and implying it the exponentially fast decay property (efd)) of conformal measures induced by 1-dimensional finite parabolic iterated function systems. We also investigate the doubling property of these measures and we estimate fro...
متن کاملA remark on densities of hyperbolic dimensions for conformal iterated function systems with applications to conformal dynamics and fractal number theory
In this note we investigate radial limit sets of arbitrary regular conformal interated function systems. We show that for each of these systems there exists a variety of finite hyperbolic subsystems such that the spectrum made of the Hausdorff dimensions of the limit sets of these subsystems is dense in the interval between 0 and the Hausdorff dimension of the given conformal iterated function ...
متن کاملGeometric Rigidity of Conformal Matrices
We provide a geometric rigidity estimate à la Friesecke-James-Müller for conformal matrices. Namely, we replace SO(n) by a arbitrary compact subset of conformal matrices, bounded away from 0 and invariant under SO(n), and rigid motions by Möbius transformations.

Introduction: Nowadays virtual colonoscopy has become a reliable and efficient method of detecting primary stages of colon cancer such as polyp detection. One of the most important and crucial stages of virtual colonoscopy is colon segmentation because an incorrect segmentation may lead to a misdiagnosis. Materials and Methods: In this work, a hybrid method based on Geometric Deformable Models...
متن کاملGeometric Rigidity for Class S of Transcendental Meromorphic Functions Whose Julia Sets Are Jordan Curves
We consider any transcendental meromorphic function f of Class S whose Julia set is a Jordan curve. We show that the Julia set of f either is an extended straight line or has Hausdorff dimension strictly greater than 1. The proof uses conformal iterated function systems and extends many earlier results of this type.
