Query: Scaling properties of the cluster distribution of a critical
  nonequilibrium model   A geometric approach to critical fluctuations of a nonequilibrium model is
reported. The two-dimensional majority vote model was investigated by Monte
Carlo simulations on square lattices of various sizes and a detailed scaling
analysis of cluster statistical and geometric properties was performed. The
cluster distribution exponents and fractal dimension were found to be the same
as those of the (two-dimensional) Ising model. This result, which cannot be
derived purely from the known bulk critical behaviour, widens our knowledge
about the range of validity of the Ising universality class for nonequilibrium
systems.
