Zusammenfassung
We study the space-time correlation and response functions in nonequilibrium growth
processes described by linear stochastic Langevin equations. Exploiting exclusively
the existence of space and time dependent symmetries of the noiseless part of these
equations, we derive expressions for the universal scaling functions of two-time
quantities which are found to agree with the exact expressions obtained from the
stochastic equations of motion. The usefulness of the space-time functions is
illustrated through the investigation of two atomistic growth models, the Family
model and the restricted Family model, which are shown to belong to a unique
universality class in 1+1 and in 2+1 space dimensions. This corrects earlier
studies which claimed that in 2+1 dimensions the two models belong to different
universality classes.\\
