چکیده

Let X be a compact connected subset of Rd with non-empty interior, and T : X → X a real analytic full branch expanding map with countably many branches. Elements of a thermodynamic formalism for such systems are developed, including criteria for compactness of transfer operators acting on spaces of bounded holomorphic functions. In particular a new sufficient condition for the existence of a T -invariant probability measure equivalent to Lebesgue measure is obtained.

Absolutely continuous invariant measures for piecewise real-analytic expanding maps on the plane

We prove the existence of absolutely continuous invariant measures for piecewise real-analytic expanding maps on bounded regions in the plane.

Singular Limits of Absolutely Continuous Invariant Measures for Families of Transitive Maps

We investigate the dependence on the parameters of absolutely continuous invariant measures for a family of piecewise linear piecewise expanding maps. We construct an example to show that the transitivity of the maps does not imply the convergence of those measures to the absolutely continuous invariant measure for the limit map.

An ergodic theoretic approach to mean eld coupled maps

We study innnite systems of globally coupled maps with permutation invariant interaction as limits of large nite-dimensional systems. Because of the symmetry of the interaction the interesting invariant measures are the exchangeable ones. For innnite systems this means in view of de Finetti's theorem that we must look for time invariant measures within the class of mixtures of spatial i.i.d. pr...

Relative Equilibrium States and Dimensions of Fiberwise Invariant Measures for Distance Expanding Random Maps

We show that the Gibbs states (known from [9] to be unique) of Hölder continuous potentials and random distance expanding maps coincide with relative equilibrium states of those potentials, proving in particular that the latter exist and are unique. In the realm of conformal expanding random maps we prove that given an ergodic (globally) invariant measure with a given marginal, for almost every...

Coupled Analytic Maps

We consider a lattice of weakly coupled expanding circle maps. We construct, via a cluster expansion of the Perron-Frobenius operator, an invariant measure for these innnite dimensional dynamical systems which exhibits space-time-chaos.
