The model of statistical physics on a countable amenable group G is considered. For the natural action of G on the space of configurations S{sup G}, |S|<{infinity}, and for any closed invariant set X subset of S{sup G} we prove that there exists pressure which corresponds to a potential with finite norm on X (in the sense of the limit with respect to any Foelner sequence of sets in G). The existence of an equilibrium measure is established. Bibliography: 8 titles.
