In the present paper the author presents a formulation of the Gibbs variational principle in an abstract manner for a triplet (X,F,m) where (X,F) is a compact dynamical system and m is a probability measure on X. This approach unifies the Donsker-Varadhan theory for Markov chains [see. e.g., M. D. Donsker and S. R. S. Varadhan, Commun. Pure Appl. Math. 36, 183-212 (1983; Zbl 0512.60068)], the equilibrium classical statistical mechanics of lattice systems [see, e.g. G. Gallavotti and S. Miracle-Sole [Commun. Math. Phys. 5, 317-323 (1967; Zbl 0154.465)] as well as the theories for symbolic dynamics, expanding maps and Anosov diffeomorphisms.
