  text: In this paper, we study small perturbations of a class of non-convex integrable
    Hamiltonians with two degrees of freedom, and we prove a result of diffusion for
    an open and dense set of perturbations, with an optimal time of diffusion which
    grows linearly with respect to the inverse of the size of the perturbation.

  text: Light-activated self-propelled colloids are synthesized and their active motion
    is studied using optical microscopy. We propose a versatile route using different
    photoactive materials, and demonstrate a multiwavelength activation and propulsion.
    Thanks to the photoelectrochemical properties of two semiconductor materials (α-Fe2O3
    and TiO2), a light with an energy higher than the bandgap triggers the reaction
    of decomposition of hydrogen peroxide and produces a chemical cloud around the
    particle. It induces a phoretic attraction with neighbouring colloids as well
    as an osmotic self-propulsion of the particle on the substrate. We use these mechanisms
    to form colloidal cargos as well as self-propelled particles where the light-activated
    component is embedded into a dielectric sphere. The particles are self-propelled
    along a direction otherwise randomized by thermal fluctuations, and exhibit a
    persistent random walk. For sufficient surface density, the particles spontaneously
    form ‘living crystals’ which are mobile, break apart and reform. Steering the
    particle with an external magnetic field, we show that the formation of the dense
    phase results from the collisions heads-on of the particles. This effect is intrinsically
    non-equilibrium and a novel principle of organization for systems without detailed
    balance. Engineering families of particles self-propelled by different wavelength
    demonstrate a good understanding of both the physics and the chemistry behind
    the system and points to a general route for designing new families of self-propelled
    particles.

  text: The classical principle of least action says that orbits of mechanical systems
    extremize action; an important subclass are those orbits that minimize action.
    In this paper we utilize this principle along with Aubry-Mather theory to construct
    (Birkhoff) regions of instability for a certain three-body problem, given by a
    Hamiltonian system of 2 degrees of freedom. We believe that these methods can
    be applied to construct instability regions for a variety of Hamiltonian systems
    with 2 degrees of freedom. The Hamiltonian model we consider describes dynamics
    of a Sun-Jupiter-comet system, and under some simplifying assumptions, we show
    the existence of instabilities for the orbit of the comet. In particular, we show
    that a comet which starts close to an orbit in the shape of an ellipse of eccentricity
    e=0.66 can increase in eccentricity up to e=0.96. In the sequels to this paper,
    we extend the result to beyond e=1 and show the existence of ejection orbits.
    Such orbits are initially well within the range of our solar system. This might
    give an indication of why most objects rotating around the Sun in our solar system
    have relatively low eccentricity.

  text: In this paper, using the ideas of Bessi and Mather, we present a simple mechanical
    system exhibiting Arnold diffusion. This system of a particle in a small periodic
    potential can be also interpreted as ray propagation in a periodic optical medium
    with a near-constant index of refraction. Arnold diffusion in this context manifests
    itself as an arbitrary finite change of direction for nearly constant index of
    refraction.

    a step towards understanding “how often does a surface diffeomorphism\r\nhave

    sinks either of cyclicity bounded by D or those\r\nwhose period is relatively

  text: We consider the evolution of a connected set on the plane carried by a space
    periodic incompressible stochastic flow. While for almost every realization of
    the stochastic flow at time t most of the particles are at a distance of order
    equation image away from the origin, there is a measure zero set of points that
    escape to infinity at the linear rate. We study the set of points visited by the
    original set by time t and show that such a set, when scaled down by the factor
    of t, has a limiting nonrandom shape.

  text: We continue the previous article's discussion of bounds, for prevalent diffeomorphisms
    of smooth compact manifolds, on the growth of the number of periodic points and
    the decay of their hyperbolicity as a function of their period $n$. In that article
    we reduced the main results to a problem, for certain families of diffeomorphisms,
    of bounding the measure of parameter values for which the diffeomorphism has (for
    a given period $n$) an almost periodic point that is almost nonhyperbolic. We
    also formulated our results for $1$-dimensional endomorphisms on a compact interval.
    In this article we describe some of the main techniques involved and outline the
    rest of the proof. To simplify notation, we concentrate primarily on the $1$-dimensional
    case.

  text: 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 $C^2$ or smoother diffeomorphisms.
    In the present work we show that, by contrast, for a measure-theoretic notion
    of genericity we call ``prevalence'', the growth is not much faster than exponential.
    Specifically, we show that for each $\delta > 0$, there is a prevalent set of
    ( $C^{1+\rho}$ or smoother) diffeomorphisms for which the number of period $n$
    points is bounded above by $\operatorname{exp}(C n^{1+\delta})$ for some $C$ independent
    of $n$. We also obtain a related bound on the decay of the hyperbolicity of the
    periodic points as a function of $n$. The contrast between topologically generic
    and measure-theoretically generic behavior for the growth of the number of periodic
    points and the decay of their hyperbolicity shows this to be a subtle and complex
    phenomenon, reminiscent of KAM theory.
