Abstract
The natural measure of a chaotic set in a phase-space region can be related to the dynamical properties of the unstable periodic orbits embedded in that set. This result has been proven to be valid for hyperbolic chaotic systems. We test the goodness of such a periodic-orbit characterization of the natural measure for nonhyperbolic chaotic systems by comparing the natural measure of a typical chaotic trajectory with that computed from unstable periodic orbits. Our results suggest that the unstable periodic-orbit formulation of the natural measure is typically valid for nonhyperbolic chaotic systems.

A description of normalized distributions (measures) lying upon possibly fractal sets; for example those arising in dynamical systems theory, focusing upon the scaling properties of such measures, which are characterized by two indices: \ensuremath{\alpha}, which determines the strength of their singularities; and f, which describes how densely they are distributed.

The idea that the infinite number of unstable periodic orbits embedded in the support of the measure provides the key to an understanding of the structure of the subsets with different singularity scalings is pursued.

This work reports rigorous results for nonhyperbolic systems: numerical orbits typically can be shadowed by true orbits for long time periods, and the Anosov-Bowen result does not apply.

A dynamical mechanism for the unshadowability of chaotic dynamical systems that lie close to computer-generated trajectories is explained through a theoretical model and identified in simulations of a typical physical system.

It is shown that although the maps are dissipative their trajectories can be derived from a Hamiltonian, which allow us to calculate unstable periodic orbits of arbitrary length finding all points to any desired accuracy.
