    • Langevin approach for the dynamics of the contact process on annealed scale-free networks 

      Boguña Espinal, Marian; Castellano, C; Pastor Satorras, Romualdo (2009-03-19)
      Article
      Open Access
      We study the dynamics of the contact process, one of the simplest nonequilibrium stochastic processes, taking place on a scale-free network. We consider the network topology as annealed, i.e., all links are rewired at each ...
    • Nonlinear q-voter model 

      Castellano, C; Muñoz, M A; Pastor Satorras, Romualdo (2009-10)
      Article
      Open Access
      We introduce a nonlinear variant of the voter model, the q-voter model, in which q neighbors (with possible repetition) are consulted for a voter to change opinion. If the q neighbors agree, the voter takes their opinion; ...
