This talk is concerned with a theorem proved by Bowen in 1973 and some generalisations via a zeta function. The theorem of Bowen asserts that closed orbits for Axiom A flows are uniformly distributed within a basic set with respect to the associated measure of maximal entropy. This paper addresses the question as to what one can say about closed orbits in relation to other equilibrium states. The main result of this paper has already been observed by J. H. Hannay and A. M. Ozorio de Almeida [J. Phys. A 17, 3429-3440 (1984)], who present what might be called a physicists proof. The present author now gives a clearer understanding of the result.
