Majority-vote on directed Erdos-Renyi random graphs

Through Monte Carlo Simulation, the well-known majority-vote model has been studied with noise on directed random graphs. In order to characterize completely the observed order-disorder phase transition, the critical noise parameter q(c), as well as the critical exponents beta/v, gamma/v and l/v have been calculated as a function of the connectivity z of the random graph.
