Majority-vote model on directed Erdos-Renyi random graphs
F. W. S. Lima, A. O. Sousa, M. A. Sumuor
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-dis…

Mortality, birth rates and retirement play a major role in demographic changes. In most cases, mortality rates decreased in the past century without noticeable decrease in fertilit…
Test of Universality in Anisotropic 3D Ising Model
M. A. Sumour, D. Stauffer, M. M. Shabat +1
Chen and Dohm predicted theoretically in 2004 that the widely believed universality principle is violated in the Ising model on the simple cubic lattice with more than only six nea…
