Hölder continuity of measures for heavy tail potentials

Abstract

For a class of potentials $\psi$ satisfying a condition depending on the roof function of a suspension (semi)flow, we show an EKP inequality, which can be interpreted as a Hölder continuity property in the weak${}^{\ast }$ norm of measures, with respect to the pressure of those measures, where the Hölder exponent depends on the $L^q$-space that $\psi$ belongs to. This also captures a new type of phase transition for intermittent (semi)flows (and maps).
