I plan to sketch results of my recent paper
joint with Juan Rivera-Letelier, concerning pressure
function $P(t)$ of potential $-t\log |f|$ for
weakly hyperbolic rational mapping $f$.
The results concern the existence of conformal and invariant
equilibrium states, analiticity of the pressure, analyticity of
dimension spectrum of Lyapunov exponents, etc. The class of mappings
includes all finitely renormalizable
polynomials without parabolic periodic orbits, infinitely renormalizable
polynomials with complex a priori bounds, Topological Collet-Eckmann maps.
