Stably ergodic approximation: two examples
نویسنده
چکیده
It has been conjectured that the stably ergodic diieomorphisms are open and dense in the space of volume-preserving, partially hyperbolic diieomorphisms of a compact manifold. In this paper we deal with two recalcitrant examples; the standard map cross Anosov and the ergodic automorphisms of the four torus. In both cases we show that they may be approximated by stably ergodic diieomorphisms which have the stable accessibility property.

Nonuniform Center Bunching and the Genericity of Ergodicity among C1 Partially Hyperbolic Symplectomorphisms
We introduce the notion of nonuniform center bunching for partially hyperbolic diffeomorphims, and extend previous results by Burns–Wilkinson and Avila–Santamaria–Viana. Combining this new technique with other constructions we prove that C1-generic partially hyperbolic symplectomorphisms are ergodic. We also construct new examples of stably ergodic partially hyperbolic diffeomorphisms.
متن کاملOn the Approximation of Complicated Dynamical Behavior
We present eecient techniques for the numerical approximation of complicated dynamical behavior. In particular, we develop numerical methods which allow to approximate SBR-measures as well as (almost) cyclic behavior of a dynamical system. The methods are based on an appropriate discretization of the Frobenius-Perron operator, and two essentially diierent mathematical concepts are used: the ide...
متن کاملRandom Evolutions toward Applica- Tions
This article gives a short and elementary presentation of random evolutions toward applications in reliability and quality engineering. At first, the following two examples are presented: dynamical stochastic systems and increment processes both in Markov media. A dynamical system in continuous time is presented since nowadays they are widely used in dynamic reliability modeling. Limit theorems...
متن کاملThe best uniform polynomial approximation of two classes of rational functions
In this paper we obtain the explicit form of the best uniform polynomial approximations out of Pn of two classes of rational functions using properties of Chebyshev polynomials. In this way we present some new theorems and lemmas. Some examples will be given to support the results.
متن کاملStochastic Approximation with Averaging Innovation
The aim of the paper is to establish a convergence theorem for multi-dimensional stochastic approximation in a setting with innovations satisfying some averaging properties and to study some applications. The averaging assumptions allow us to unify the framework where the innovations are generated (to solve problems from Numerical Probability) and the one with exogenous innovations (market data...
