We prove that given a Holder continuous potential phi satisfying a summability condition, there exists non-lacunary Gibbs measure for phi, with positive Lyapunov exponents and infinitely many hyperbolic times almost everywhere. Moreover, this non-lacunary Gibbs measure is an equilibrium measure for phi.842-863engGibbs measuresEquilibrium statesThermodynamical formalismNon-uniform expansionArtigo10.1007/s10955-009-9811-4WOS:000270341500003Acesso restrito0000-0002-9304-0655
