Effects of mass media on opinion spreading in the Sznajd sociophysics model
In this work we consider the influence of mass media in the dynamics of the
two-dimensional Sznajd model. This influence acts as an external field, and it
is introduced in the model by means of a probability of the agents to
follow the media opinion. We performed Monte Carlo simulations on square
lattices with different sizes, and our numerical results suggest a change on
the critical behavior of the model, with the absence of the usual phase
transition for . Another effect of the probability is to
decrease the average relaxation times , that are log-normally
distributed, as in the standard model. In addition, the values depend on
the lattice size in a power-law form, , where the
power-law exponent depends on the probability .Comment: 11 pages, 8 figures, to appear in Physica
