We study the period function T of a center O of a Liénard system. A sufficient condition for the monotonicity of T, or for the isochronicity of O, is given. Such a condition is also necessary when f and g are analytic, and g is odd. In this case a characterization of isochronous centers of Liénard systems is given. Strict monotonicity and global monotonicity of T are also investigated. Copyright 1999 Academic Press.
