Thermodynamic formalism for interval maps.
Thermodynamic formalism; Equilibrium states; Zooming measures; Expanding measures.
The aim of this work is to present some of the known results about the existence and uniqueness of equilibrium states for transitive interval maps. For this, we do not use the more classical approach of Hofbauer-Keller Towers, we used zooming measures (generalizations of expanding measures) and Markov maps induced by zooming returns. With this we obtain results on the equilibrium states among the expanding measures and, for Hölder potentials that favor the expansive measures, we show the existence and uniqueness of the equilibrium state.
