Random Wandering Around Homoclinic - like Manifolds in Symplectic Map Chain
نویسنده
چکیده
We present a method to construct a symplecticity preserving renormalization group map of a chain of weakly nonlinear symplectic maps and obtain a general reduced symplectic map describing its long-time behaviour. It is found that the modulational instability in the reduced map triggers random wandering of orbits around some homoclinic-like manifolds, which is understood as the Bernoulli shifts. ∗e-mail: [email protected]

Exponentially small oscillation of 2-dimensional stable and unstable manifolds in 4-dimensional symplectic mappings
Homoclinic bifurcation of 4-dimensional symplectic mappings is asymptotically studied. We construct the 2-dimensional stable and unstable manifolds near the submanifolds which experience exponentially small splitting, and successfully obtain exponentially small oscillating terms in the 2-dimensional manifolds. ∗ E-mail address: [email protected] 1 typeset using PTPTEX.sty <ver...
متن کاملOrder of Appearance of Homoclinic Points for the Hénon Map
For the areaand orientation-preserving Hénon map,1) we previously derived a generalized dynamical ordering of the symmetric periodic orbits appearing through saddle-node bifurcations.2) The procedure consists of, first, fixing the homoclinic tangency of the stable and unstable manifolds of a saddle fixed point and, then, deriving dynamical order relations for the symmetric periodic orbits assoc...

متن کاملAsymptotic expansion of 1-dimensional sub-manifolds of stable and unstable manifolds in a 4-dimensional symplectic mapping
We analytically compute asymptotic expansions of a 1-dimensional submanifold of stable and unstable manifolds in a 4-dimensional symplectic mapping by using the method called asymptotic expansions beyond all orders. This method enables us to capture exponentially small splitting of separatrices and also to obtain explicit functional approximations of the sub-manifolds. In addition, we show the ...
متن کاملErgodic Properties of Anosov Maps with Rectangular Holes
We study Anosov diieomorphisms on manifolds in which somèholes' are cut. The points that are mapped into those holes disappear and never return. The holes studied here are rectangles of a Markov partition. Such maps generalize Smale's horseshoes and certain open billiards. The set of nonwandering points of a map of this kind is a Cantor-like set called repeller. We construct invariant and condi...
