Abstract We show that equilibrium states μ of a function φ on ([0,1], T), where T is piecewise monotonic, have strong ergodic properties in the following three cases: (i) sup φ — inf φ <htop(T) and φ is of bounded variation. (ii) φ satisfies a variation condition and T has a local specification property. (iii) φ = —log |T′|, which gives an absolutely continuous μ, T is C2, the orbits of the critical points of T are finite, and all periodic orbits of T are uniformly repelling. 
Equilibrium States for Interval Maps: Potentials with sup φ − inf φ < htop(f)
We study an inducing scheme approach for smooth interval maps to prove existence and uniqueness of equilibrium states for potentials φ with the ‘bounded range’ condition sup φ − inf φ < htop(f),
We study an inducing scheme approach for smooth interval maps to prove existence and uniqueness of equilibrium states for potentials φ with the ‘bounded range’ condition supφ − inf φ < htop(f), first
Piecewise invertible dynamical systems
SummaryThe aim of the paper is the investigation of piecewise monotonic maps T of an interval X. The main tool is an isomorphism of (X, T) with a topological Markov chain with countable state space
Positive entropy equilibrium states
For transitive shifts of finite type, and more generally for shifts with specification, it is well-known that every equilibrium state for a Holder continuous potential has positive entropy as long as
A note on two approaches to the thermodynamic formalism
Inducing schemes provide a means of using symbolic dynamics to study equilibrium states of non-uniformly hyperbolic maps, but necessitate a solution to the liftability problem. One approach, due to
On “Thermodynamics” of Rational Maps I. Negative Spectrum
We study the pressure spectrum P(t) of the maximal measure for arbitrary rational maps. We also consider its modified version P̃ (t) which is defined by means of the variational principle with
Fair measure and fair entropy for non-Markov interval maps
This paper extends several results in [8] to the non-Markov setting, and proves that for each symmetric tent map the fair entropy is equal to the topological entropy if and only if the slope isequal to 2.
An optimal transportation approach to the decay of correlations for non-uniformly expanding maps
We consider the transfer operators of non-uniformly expanding maps for potentials of various regularity, and show that a specific property of potentials (‘flatness’) implies a Ruelle–Perron–Frobenius


Examples for the nonuniqueness of the equilibrium state
In this paper equilibrium states on shift spaces are considered. A uniqueness theorem for equilibrium states is proved. Then we study a particular class of continuous functions. We characterize the
On intrinsic ergodicity of piecewise monotonic transformations with positive entropy
We consider a class of piecewise monotonically increasing functionsf on the unit intervalI. We want to determine the measures with maximal entropy for these transformations. In part I we construct a

Abstract Transformations on [0, 1] which are piecewise monotonic and piecewise continuous are considered. Using symbolic dynamics, the structure of their nonwandering set is determined. This is then
What is ergodic theory
Ergodic theory involves the study of transformations on measure spaces. Interchanging the words “measurable function” and “probability density function” translates many results from real analysis to

On intrinsic ergodicity of piecewise monotonic transformations with positive entropy II
The results about measures with maximal entropy, which are proved in [3], are extended to the following more general class of transformations on the unit intervalI : I=∪i=1/nJi, theJi are disjoint
Some Dynamical Properties of Certain Differentiable Mappings of an Interval
This paper is a continuation of the paper [S]. We present here a sufficient condition for the existence of invariant measure (absolutely continuous with respect to Lebesgue measure) for
