"Anomalous heat conduction in nonlinear and stochastic systems"

The analysis of nonlinear chains in contact with two heat baths has
has helped to understand the behaviour of systems steadily kept out of
equilibrium. I'll summarize the main results by illustrating the universal
scenario that has emerged from both simulations and theoretical arguments.
This analysis will be complemented by a detailed analytical discussion of
a stochastic model (with conservative noise) which helps to shed further light on the expected behaviour.
