For diffeomorphisms of smooth compact manifolds, we consider the problem of how fast the number of periodic points with period n grows as a function of n. In many familiar cases (e.g., Anosov systems) the growth is exponential, but arbitrarily fast growth is possible; in fact, the first author has shown that arbitrarily fast growth is topologically (Baire) generic for C2 or smoother diffeomorphisms. In the present work we show that, by contrast, for a measure-theoretic notion of genericity we…

Stretched exponential estimates on growth of the number of periodic points for prevalent diffeomorphisms I
For diffeomorphisms of smooth compact finite-dimensional manifolds, we consider the problem of how fast the number of periodic points with period $n$ grows as a function of $n$. In many familiar
Newton interpolation polynomials, discretization method, and certain prevalent properties in dynamical systems
We describe a general method of studying prevalent properties of diffeomorphisms of a compact manifold M, where by prevalent we mean true for Lebesgue almost every parameter a in a generic
On generic G-prevalent properties and a quantitative K-S theorem for Cr diffeomorphisms of the circle
An estimation of the amount of hyperbolicity in a setting that was not considered before is presented, and a kind of quantitative Kupka–Smale theorem is shown.
Dynamical profile of a class of rank-one attractors

In the 1970s, Nekhorochev proved that, for an analytic nearly integrable Hamiltonian system, the action variables of the unperturbed Hamiltonian remain nearly constant over an exponentially long time
Generic 3-dimensional volume-preserving diffeomorphisms with superexponential growth of number of periodic orbits
Let $M$ be a compact manifold of dimension three with a non-degenerate volume form $\Omega$ and Diff$^r_\Omega(M)$ be the space of $C^r$-smooth ($\Omega$-) volume-preserving diffeomorphisms of $M$
Résumé. — Katok’s theorem on C1+ smooth surface diffeomorphisms shows that their dynamics can be approximated in entropy by uniformly hyperbolic invariant sets in contrast to the case of
Super-exponential growth of the number of periodic orbits inside homoclinic classes
We show that there is a residual subset $\S (M)$ of Diff$^1$ (M) such that, for every $f\in \S(M)$, any homoclinic class of $f$ containing periodic saddles $p$ and $q$ of indices $\alpha$ and

An extension of the Artin-Mazur theorem
Let M be a compact manifold. We call a mapping f in C^r(M,M) an Artin-Mazur mapping if the number of isolated periodic points of f^n grows at most exponentially in n. Artin and Mazur posed the

Abstract Let Mm be a compact, m-dimensional smooth manifold. The n-periodic point x of a diffeomorphism f: M → M is called γ-hyperbolic, for γ≥O, if the eigenvalues λj, of dfn(x) satisfy . We prove
Homoclinic Tangencies of an Arbitrary Order in Newhouse Domains
This paper is devoted to the study of complex and unexpected phenomena that are observed in twodimensional mappings (or in three-dimensional flows) with homoclinic tangencies. In particular, we show

Our aim is to show that the Julia-Fatou--Sullivan structure theory for the dynamics of rational maps is also valid for smooth endomorphisms of the circle (and of the interval) under extremely mild
