The pressure function for infinite equilibrium measures
Abstract
Assume that (X,f) is a dynamical system and ϕ:X→[−∞,∞) is a potential such that the f-invariant measure μϕ equivalent to ϕ-conformal measure is infinite, but that there is an inducing scheme F=fτ with a finite measure μϕ¯ and polynomial tails μϕ¯(τ≥n) = O(n−β), β∈(0,1). We give conditions under which the pressure of f for a perturbed potential ϕ+sψ relates to the pressure of the induced system as P(ϕ+sψ) = (CP(ϕ+sψ))1/β(1+o(1)), together with estimates for the o(1)-error term. This extends results from Sarig to the setting of infinite equilibrium states. We give several examples of such systems, thus improving on the results of Lopes for the Pomeau-Manneville map with potential ϕt=−tlogf′, as well as on the results by Bruin & Todd on countably piecewise linear unimodal Fibonacci maps. In addition, limit properties of the family of measures μϕ+sψ as s→0 are studied and statistical properties (correlation coefficients and arcsine laws) under the limit measure are derived.
