*/Thermodynamics for Lebesgue dissipative interval maps/*/./

/_Abstract:_//Using inducing schemes (generalised first return maps) to 
obtain uniform expansion is a standard tool for (smooth) interval
maps, in order to prove, among other things, the existence of invariant 
measures, their mixing rates and stochastic laws. In this talk I
would like to present joint work with Mike Todd (St Andrews) on how this 
can be applied to maps on the brink of being dissipative.
We discuss a family f of Fibonacci maps for which Lebesgue-a.e. point is 
recurrent or transient depending on the parameter . The
main tool is a specific induced Markov map F with countably many 
branches whose lengths converge to zero. Avoiding the diffculties
of distortion control by starting with a countably piecewise linear 
unimodal map, we can identify the tran- sition from conservative to
dissipative exactly, and also describe in great detail the impact of 
this transition on the thermodynamic formalism of the system
(existence and uniqueness of equilibrium states, (non)analyticity of the 
pressure function and phase transi-tions)./
