Abstract


This work is concerned with zeta functions of two-dimensional shifts of finite type. A two-dimensional zeta function , which generalizes the Artin-Mazur zeta function, was given by Lind for -action . In this paper, the th-order zeta function of on , , is studied first. The trace operator , which is the transition matrix for -periodic patterns with period and height , is rotationally symmetric. The rotational symmetry of induces the reduced trace operator and . The zeta function in the -direction is now a reciprocal of an infinite product of polynomials. The zeta function can be presented in the -direction and in the coordinates of any unimodular transformation in . Therefore, there exists a family of zeta functions that are meromorphic extensions of the same analytic function . The natural boundary of zeta functions is studied. The Taylor series for these zeta functions at the origin are equal with integer coefficients, yielding a family of identities, which are of interest in number theory. The method applies to thermodynamic zeta functions for the Ising model with finite range interactions.
