to accomodate wide classes of non-uniformly hyperbolic dynamics and yet keep most of the basic features of S.F.T. Therefore a key problem is to enlarge S.F.T. are much too rigid to provide a description of more general dynamics (for instance, there are only countably many topological conjugacy classes of S.F.T.). They have been thoroughly studied (see, e.g., ) and this result has been generalized to all uniformly hyperbolic systems (see, e.g., ). Such subsets are now called subshifts of finite type (or S.F.T.). Motivated by the powerful techniques provided by the use of the Artin-Mazur zeta-functions in number theory and the use of the Ruelle zeta-functions in dynamical systems, Lapidus and collaborators (see books by Lapidus & van Frankenhuysen 32, 33 and the references therein) have introduced and pioneered use of zeta-functions in fractal geometry. Namely, these subsets are defined by excluding a finite number of words. We define the ArtinMazur zeta function for to be the function (1.2).
