Abstract
We analyse the Langevin dynamics of the random walk, the scalar field, the X-Y model and the
spinoidal decomposition. We study the deviations from the equilibrium dynamics theorems (FDT
and homogeneity), the asymptotic behaviour of the systems and the aging phenomena. We compare
the results with the dynamcal behaviour of (random) spin-glass mean-field models.
