Symbolic Dynamics and Markov Partitions for the Stadium Billiard

  • Kai T. Hansen
چکیده

We investigate the Bunimovich stadium dynamics and nd that in the limit of innnitely long stadium the symbolic dynamics is a subshift of nite type. For a stadium of nite length the Markov partitions are innnite, but the inadmissible symbol sequences can be determined exactly by means of the appropriate pruning front. We outline a construction of a sequence of nite Markov graph approximations by means of approximate pruning fronts with nite numbers of steps.

Symbolic Dynamics Ii the Stadium Billiard

We construct a well ordered symbolic dynamics plane for the stadium billiard. In this symbolic plane the forbidden and the allowed orbits are separated by a monotone pruning front, and allowed orbits can be systematically generated by sequences of approximate finite grammars. 1 ‡ Permanent address: Phys Dep., University of Oslo, Box 1048, Blindern, N-0316 Oslo

Some dynamical properties of the stadium billiard

We consider the dynamical properties of one kind of cyclically ordered orbits of the stadium billiard. We prove that the stadium billiard possesses infinitely many such orbits, that they are hyperbolic, and that their stable and unstable manifolds intersect transversely. Hence the stadium billiard contains a Smale horseshoe. We construct symbolic dynamics for these orbits and consider their sen...

Symbolic Dynamics and the Discrete Variational Principle

We show how to construct symbolic dynamics for the class of 2d-dimensional twist mappings generated by piecewise strictly convex/concave generating functions. The method is constructive and gives an eecient way to nd all periodic orbits of these high dimensional symplectic mappings. It is illustrated with the cardioid and the stadium billiard.

How does a choice of Markov partition affect the resultant symbolic dynamics?

The mutual relationship among Markov partitions is investigated for one-dimensional piecewise monotonic map. It is shown that if a Markov partition is regarded as a map-refinement of the other Markov partition, that is, a concept we newly introduce in this article, one can uniquely translate a set of symbolic sequences by one Markov partition to those by the other or vice versa. However, the se...

Markov Partitions and Homoclinic Pointsof

We prove that a general class of expansive Z d-actions by automorphisms of compact, abelian groups with completely positive en-tropy has`symbolic covers' of equal topological entropy. These symbolic covers are constructed by using homoclinic points of these actions. For d = 1 we adapt a result of Kenyon and Vershik in 7] to prove that these symbolic covers are, in fact, sooc shifts. For d 2 we ...
