✦ Synopsis

We study the e ect of signal cooperation in a 2D cellular-automaton model of tra c ow in cities. Two-state signals, which permit vertical or horizontal passage of vehicles, are introduced to all cells of the automaton system. We simulate the dynamics of vehicles for di erent samples of signal arrangement. Phase transition occurs between freely moving and jamming phases for the samples. The critical densities for the transition vary as the arrangement is changed. We ΓΏnd a case having the multistage transition between them. The origin of the behavior is examined.

The two-dimensional Ising model with nearest-and next-nearest-neighbor antiferromagnetic interactions of ratio R is simulated on the Creutz cellular automaton. The values of the critical temperature and the critical exponents for 0 ~<R < 5 are estimated within the framework of the finite size scalin

We propose a new model which reduces a two-dimensional gravitational model with dynamical metric and torsion in a conformal gauge. We also find the instanton-like solutions and discuss their symmetry properties and eigenmodes.
