Equality of HÃ¶lder exponents for distribution functions of Gibbs measures

Pieter Allaart, Johannes Jaerisch

Pointwise HÃ¶lder exponents describe the degree of regularity of a function near a point. For a function $f : R \to R$ , a number $I^\pm > 0$ and a point $t_{0} \in R$ …

Dimension gap and phase transition for one-dimensional random walks with reflective boundary

Maik GrÃ¶ger, Johannes Jaerisch, Marc KessebÃ¶hmer

We study $Z$ - and $N$ -extensions of interval maps with at most countably many full branches modelling one-dimensional random walks without and with a reflective bou…

Amenable graphs and the spectral radius of extensions of Markov maps

Johannes Jaerisch, Elaine Rocha, Manuel Stadlbauer

We discuss relations between the amenability of a graph and spectral properties of a random walk driven by a dynamical system. In order to include graphs which are not locally comp…
