Typical Dynamics of Volume Preserving Homeomorphisms by Steve Alpern

As the identity homeomorphism on X has these properties, it follows that any manifold supports an ergodic homeomorphism. New proofs that weak mixing is generic. Thus the decomposition of A1. This means that all the column heights of the skyscraper {Ak,i } are multiples of p. There are of course many types of properties that a measure preserving homeomorphism might possess. We shall call a property typical, or generic, if the set of points with this property contains a dense Gδ set. In Measure theory and its applications Sherbrooke, Que.

Since an ergodic automorphism is necessarily antiperiodic, V must contain an antiperiodic automorphism. Review of the hardback: 'An interesting piece of research for the specialist. A key idea here is the interrelation between typical properties of volume preserving homeomorphisms and typical properties of volume preserving bijections of the underlying measure space. To these and others our sincere thanks for their contributions. The following result is restated in Chapter 16 in a notation better suited to the applications in that section. We would like to apply Lemma 7.

The P j are constructed as follows. On a personal note V. The authors make the first part of this book very concrete by considering volume preserving homeomorphisms of the unit n-dimensional cube, and they go on to prove fixed point theorems Conley-Zehnder- Franks. John Oxtoby and Stan Ulam, to whom the book is dedicated, guided our subsequent investigations on which this book is based. It follows from Lemma 14. Much of this work describes the work of the two authors, over the last twenty years, in extending to different settings and properties, the celebrated result of Oxtoby and Ulam that for volume homeomorphisms of the unit cube, ergodicity is a typical property.

Of course there is nothing special about the dyadic cubes of order m obtained by dividing each axis of I n in half m times. There is always of course the identity map. This is because we have organized the proofs so that all these diverse observations are consequences of a single result, which we state below as Theorem 15. Return times and conjugates of an antiperiodic transformation. We develop the results of both authors in establishing positive and negative results regarding the typicality of certain properties on various manifolds. A 0-cube is simply the center of a dyadic cube. Let denote the group of homeomorphisms of a σ-compact manifold M which preserve a locally positive non-atomic measure μ.

Sichuan Daxue Xuebao, 27 1 :27—28, 1990. We then present examples of manifolds where ergodicity is not typical. Then appealing to the Homeomorphic Measures Theorem exactly as above, we extend fˆ to a volume preserving homeomorphism of C1. A state i is called recurrent if the Markov chain with matrix P starting at i returns eventually to i with probability 1. When P is irreducible the period of every state is the same and is called the period of the matrix P. Fixed points of measure preserving torus homeomorphisms.

Recurrence in ergodic theory and combinatorial number theory. This general framework involves the following notions: i ii iii iv The The The The ends of a noncompact manifold induced homeomorphism on the ends compressibility of the induced homeomorphism charge on an invariant set of ends. These results apply more generally to compact manifolds. We show that any abstract ergodic behavior typical for automorphisms of Mn,π. Examples of properties of homeomorphisms considered include transitivity, chaos and ergodicity. Our combimorphism h, whose lift h natorial proof of this fact is given in Theorem 3.

Pure and applied Mathematics, Vol. We wanted to show that on every manifold a space representing the possible states of a dynamical system — the kind used in statistical mechanics — such ergodic behavior is the rule. Examples of properties of homeomorphisms considered include transitivity, chaos and ergodicity. In this section we extend that result to show that, as for compact manifolds, any ergodic theoretical property typical for automorphisms of the underlying measure space is also typical for volume preserving homeomorphisms. We observed earlier that if µ X 0. The reader is urged to review that section and in particular to read the statement of Lemma 7. Maximally chaotic homeomorphisms of sigma-compact manifolds.

Examples of properties of homeomorphisms considered include transitivity, chaos and ergodicity. Measures on compact manifolds; 10. We describe these compact connected submanifolds and these special properties. This section is an extension of the results of Section 4. In that proof we used the Lusin Theorem 10. Examples of such measure theoretic properties are ergodicity, weak mixing, and zero entropy.

In Topology of 3-manifolds and related topics Proc. Surveys, 25 1970 , 191—220. The Clarendon Press Oxford, University Press, New York, 1995. This is done in a number of short self-contained chapters which would be suitable for an undergraduate analysis seminar or a graduate lecture course. Although we will not need to deal with such problems we do note that the end sets may be embedded in S 2 in a very complicated fashion. To prove that these manifolds are counterexamples to generic ergodicity however, we have to show moreover that any area preserving homeomorphism near enough to t in the compact-open topology is also nonrecurrent. That is, how far can we generalize Theorem 12.

Morton Brown and Herman Gluck. The purpose of this section is to show 12. The proof of Theorem 15. We shall further call R a π-skyscraper of type j, if it has no column heights larger than j i. This means that for almost every point x in I n , x is periodic ¯ and in fact belongs to a closed cube on which h ¯ acts rigidly and under h, hence linearly. On manifolds with an additive structure which leaves the measure invariant e. This concept is applied in the following lemma.
