Regular potentials of additive functionals in semidynamical systems

Nedra Belhaj Rhouma; Mounir Bezzarga — 2004

Commentationes Mathematicae Universitatis Carolinae

We consider a semidynamical system $(X, ℬ, Φ, w)$ . We introduce the cone $𝔸$ of continuous additive functionals defined on $X$ and the cone $𝒫$ of regular potentials. We define an order relation “ $\leq$ ” on $𝔸$ and a specific order “ $≺$ ” on $𝒫$ . We will investigate the properties of $𝔸$ and $𝒫$ and we will establish the relationship between the two cones.
