Spatial Recurrence for Ergodic Fractal Measures
نویسنده
چکیده
We study the invertible version of Furstenberg’s ‘Ergodic CP Shift Systems’, which describe a random walk on measures on Euclidean space. These measures are by definition invariant to a scaling procedure, and satisfy a condition called adaptedness under a ”local” translation operation. We show that the distribution is in fact non-singular with respect to a suitably defined translation operator on measures, and derive discrete and continuous pointwise ergodic theorems for the translation action.

Hausdorff and packing dimensions for ergodic invariant measures of two-dimensional Lorenz transformations
We extend the notions of Hausdorff and packing dimension introducing weights in their definition. These dimensions are computed for ergodic invariant probability measures of two-dimensional Lorenz transformations, which are transformations of the type occuring as first return maps to a certain cross section for the Lorenz differential equation. We give a formula of the dimensions of such measur...
متن کاملEntropy and Poincaré Recurrence from a Geometrical Viewpoint
We study Poincaré recurrence from a purely geometrical viewpoint. In [8] it was proven that the metric entropy is given by the exponential growth rate of return times to dynamical balls. Here we use combinatorial arguments to provide an alternative and more direct proof of this result and to prove that minimal return times to dynamical balls grow linearly with respect to its length. Some relati...
متن کاملErgodic Properties of Anosov Maps with Rectangular Holes
We study Anosov diieomorphisms on manifolds in which somèholes' are cut. The points that are mapped into those holes disappear and never return. The holes studied here are rectangles of a Markov partition. Such maps generalize Smale's horseshoes and certain open billiards. The set of nonwandering points of a map of this kind is a Cantor-like set called repeller. We construct invariant and condi...
متن کاملاستفاده از بعد فراکتالی برای بررسی اثر مقیاس بر حساسیت سنجههای سیمای سرزمین
The sensitivity of landscape metrics to the scale effect is one of the most challenging issues in landscape ecology and quantification of land use spatial patterns. In this study, fractal dimension was employed to assess the effect of scale on the sensitivity of landscape metric in the north of Iran (around Sari) as the case study. Land use/ cover maps were derived from Landsat-8 (OLI sensor) i...
متن کاملDimension and Ergodic Decompositions for Hyperbolic Flows
For conformal hyperbolic flows, we establish explicit formulas for the Hausdorff dimension and for the pointwise dimension of an arbitrary invariant measure. We emphasize that these measures are not necessarily ergodic. The formula for the pointwise dimension is expressed in terms of the local entropy and of the Lyapunov exponents. We note that this formula was obtained before only in the speci...
