A nonequilibrium-potential approach to competition in neural populations
R. R. Deza, J. I. Deza, N. Martinez +2
Energy landscapes are a useful aid for the understanding of dynamical systems, and a valuable tool for their analysis. For a broad class of rate models of neural networks, we deriv…
Discretization-related issues in the KPZ equation: Consistency, Galilean-invariance violation, and fluctuation--dissipation relation
H. S. Wio, J. A. Revelli, R. R. Deza +2
In order to perform numerical simulations of the KPZ equation, in any dimensionality, a spatial discretization scheme must be prescribed. The known fact that the KPZ equation can b…
Competition Among Companies: Coexistence and Extinction
Marcelo Kuperman And Horacio Wio
We study a spatially homogeneous model of a market where several agents or companies compete for a wealth resource. In analogy with ecological systems the simplest case of such mod…
On the Influence of Noise on the Critical and Oscillatory Behavior of a Predator-Prey Model: Coherent Stochastic Resonance at the Proper Frequency
A. F. Rozenfeld, C. J. Tessone, E. Albano +1
Noise induced changes in the critical and oscillatory behavior of a Prey-Predator system are studied using power spectrum density and Spectral Amplification Factor (SAF) analysis.…
Nonequilibrium phase transitions induced by multiplicative noise: effects of self-correlation
S. E. Mangioni, R. R. Deza, R. Toral +1
A recently introduced lattice model, describing an extended system which exhibits a reentrant (symmetry-breaking, second-order) noise-induced nonequilibrium phase transition, is st…
Disordering effects of color in nonequilibrium phase transitions induced by multiplicative noise
S. Mangioni, R. Deza, H. S. Wio +1
The model introduced by Van den Broeck, Parrondo and Toral [Phys. Rev. Lett.73, 3395 (1994)] -- leading to a second-order-like noise-induced nonequilibrium phase transition which s…
