Abstract
We use Monte Carlo simulation to study new features of the (one-dimens ional) Domany-Kinzel cellular automaton (CA). Considering the relaxati on process of the 'magnetization' (the frozen-active order parameter) towards its equilibrium value, we measure its dynamical critical expon ent z. Also, we investigate the effect of p0 not-equal 0 (non-vanishin g external field conjugate to the magnetization) on the phase diagram and on the susceptibility. Finally, we introduce constraints in the ev olution rule of the Domany-KinZel CA and study the associated critical ity (critical surfaces and universality classes).
