title: Dimensional reduction in a model with infinitely many absorbing states.
abstract: Using the Monte Carlo method, we study a two-dimensional model with infinitely many absorbing states. Our estimation of the critical exponent beta is approximately equal to 0.273(5) suggests that the model belongs to the (1+1) rather than to (2+1) directed-percolation universality class. We also show that for a large class of absorbing states the dynamic Monte Carlo method leads to spurious dynamical transitions.
