|The functional dependence of linear response functions
on correlation functions is regulated, for every equilibrium
system, by the fluctuation-dissipation theorem.
Although such a generality does not hold out of equilibrium,
fluctuation-dissipation relations still encode basic universal
properties of broad classes of systems.
In particular, I will focus on the phase-ordering
kinetics following a quench to an ordered phase,
showing the robustness of the fluctuation-dissipation relation when
specific details, as the topology of the lattice or
the microscopic dynamical rule, are changed.
