Statistical properties in hyperbolic dynamics




S1.
Rufus Bowen, Markov partitions for Axiom A diffeomorphisms, Amer. J. Math. 92 (1970), p. 725-747.

This paper proves that uniformly hyperbolic systems can be modeled with subshifts of finite type.

Compared to S1, this is more readable and uses a different approach (more transparent and indeed better). This, and not the approach from Bowen's 1970 paper, is the approach that Sarig generalizes for surface diffeos.


S2.
C. Liverani, Central limit theorem for deterministic systems, in International Conference on Dynamical Systems (Montevideo, 1995), 56-75, Pitman Res. Notes Math. Ser., 362, Longman, Harlow, 1996.

preprint on Liverani's page

Once it has been proved that correlations decay quickly enough, the CLT can be derived using martingale approximations.

Carlangelo Liverani, Benoit Saussol, and Sandro Vaienti. A probabilistic approach to intermittency. Ergodic Theory Dynam. Systems 19 (1999), no. 3, 671-685.

The first paper carries out the details of the proof of decay of correlations using the method of cones and the Hilbert metric, which might be discussed in Will Ott's lectures.
The second extends this to some non-uniformly hyperbolic dynamical systems, which display "intermittent" chaotic behavior. NOTE that although a particular cone plays a central role, this is not related to the Hilbert metric.

Self-contained proof - with background on BV - of exponential decay of correlations for piecewise-expanding maps on the interval, including the Lasota-Yorke inequality.

A clean discussion of exponential decay of correlations for Gibbs-Markov maps (includes full-branch piecewise expanding interval maps)


Statistical mechanics and thermodynamic formalism




T1

Bowen, Rufus. Equilibrium states and the ergodic theory of Anosov diffeomorphisms, Chapter 1. Second revised edition. With a preface by David Ruelle. Edited by Jean-René Chazottes. Lecture Notes in Mathematics, 470. Springer-Verlag, Berlin, 2008. viii+75 pp.

Develops the general theory of Gibbs measures for Holder continuous potential functions on topological Markov chains, starting with the motivation from thermodynamics.


T2

Bowen, Rufus. Some systems with unique equilibrium states. Math. Systems Theory 8 (1974/75), no. 3, 193-202.

Gives an approach to existence and uniqueness of equilibrium states that does not use any symbolic coding of the system, but rather relies on the "specification" property, which stipulates that an arbitrary collection of finite-length trajectories of the system can be shadowed by a single trajectory that takes a uniformly bounded time to transition from one orbit segment to the next.


T3

D.V. Anosov, A.V. Klimenko, G. Kolutsky. On the hyperbolic automorphisms of the 2-torus and their Markov partitions, (2008), arXiv:0810.5269

Starts with a discussion of how to treat deterministic systems as random processes, then constructs Markov partitions on the 2-torus for hyperbolic automorphisms, which lets these systems be viewed as Markov shifts. This was the first example of Markov partitions historically and is simpler than the general construction by Bowen in S1. The paper also includes some results on classification of Markov partitions.


T4

Lai-Sang Young. What are SRB measures, and which dynamical systems have them?   J. Stat Phys 108, No 5/6 (2002), 733-754.

The use of mathematical methods from statistical mechanics to construct a physically relevant SRB measure for smooth hyperbolic dynamical systems is one of the crowning achievements of thermodynamic formalism. This survey paper gives an overview.
