Webb31 mars 2024 · The threshold conditions for the occurrence of Smale-horseshoe chaos of this deterministic system are obtained. Compared with the existing conclusion, i.e. the smaller the damping term is, the easier the chaotic motions become when the damping term is linear, our analysis, however, finds that the smaller or the larger the damping … In the mathematics of chaos theory, a horseshoe map is any member of a class of chaotic maps of the square into itself. It is a core example in the study of dynamical systems. The map was introduced by Stephen Smale while studying the behavior of the orbits of the van der Pol oscillator. The action of the map is … Visa mer The horseshoe map f is a diffeomorphism defined from a region S of the plane into itself. The region S is a square capped by two semi-disks.

Webb7 maj 2014 · We consider the family of quadratic Hénon diffeomorphisms of the plane ${\\bf R}^2$. A map will be said to be a "horseshoe" if its restriction to the nonwandering set is hyperbolic and conjugate to the full 2-shift. We give a criterion for being a horseshoe based on an auxiliary coding which describes positions of points relative to the stable … WebbWe study hyperbolic dynamics and bifurcations for generalized Hénon maps in the form (with b, α small and γ > 4).

Webb1 apr. 2006 · As a consequence, the anti-integrability of the Hénon map H a,b can be correlated with that of the Smale horseshoe. We show the dynamics of a horseshoe which has uniformly contraction rate ϵ and expansion rate 1/ ϵ behaves the same as that of Fig. 1: the limit lim a →∞ H a , b corresponds to the limit ϵ → 0.

Webb20 okt. 2024 · In 1960 Stephen Smale (building on work by David Birkhoff) proved that the horseshoe is in some sense universal. A large class of dynamical systems, defined by mathematical equations, contain the dynamics of the horseshoe map and therefore also contain its chaos.
