Dynamical Zeta Functions for Piecewise Monotone Maps Interva

Consider a space $M$, a map $f:Mo M$, and a function $g:M o {Bbb C $. The formal power series $zeta(z) = exp sum infty_{m=1 rac{z {m sum_{x in oman{Fix ,f prod m-1 _{k=0 g (f x)$ yields an example of a dynamical zeta function. Such functions have unexpected analytic properties and interesting relations to the theory of dynamical systems, statistical mechanics, and the spectral theory of certain operators (transfer operators). The first part of this monograph presents a general introduction to this subject. The second part is a detailed study of the zeta functions associated with piecewise monotone maps of the interval $[0,1]$. In particular, Ruelle gives a proof of a generalized form of the Baladi-Keller theorem relating the poles of $zeta (z)$ and the eigenvalues of the transfer operator. He also proves a theorem expressing the largest eigenvalue of the transfer operator in terms of the ergodic properties of $(M,f,g)$. This series is published by the AMS for the Centre de Recherches Math'ematiques.;This book is intended for researchers in mathematics and mathematical physics.
