  These are notes from a course given in Orsay in 2002 explaining carefully the
Milnor-Thurston kneading determinant approach to dynamical zeta functions as
interpreted by Baladi and Ruelle (Invent. Math. 1996). We make them available
in view of the recent renewed interest in this approach. (see arXiv:1501.00294,
