Abstract
We study numerically the short-time critical dynamical behavior of a f amily of nonequilibrium models with up-down symmetry. Our numerical re sults show that these models, which include the Glauber dynamics as a particular case, present short-time universality. The exponent theta i s calculated from the early time behavior of the time correlation of t he total magnetization [m(t)m(0)] by starting from an initial state wi th zero correlation length and zero magnetization.
