Título: | Scale-invariance underlying the logistic equation and its social applications |
Autor: | Hernando de Castro, Alberto; Plastino, A. | Palabras clave: | Logistic equation Scale-invariance Social systems |
Fecha de publicación: | 3-ene-2013 | Editor: | Elsevier | Citación: | Physics Letters A 377(3-4): 176-180 (2013) | Resumen: | On the basis of dynamical principles we i) advance a derivation of the Logistic Equation (LE), widely employed (among multiple applications) in the simulation of population growth, and ii) demonstrate that scale-invariance and a mean-value constraint are sufficient and necessary conditions for obtaining it. We also generalize the LE to multi-component systems and show that the above dynamical mechanisms underlie a large number of scale-free processes. Examples are presented regarding city-populations, diffusion in complex networks, and popularity of technological products, all of them obeying the multi-component logistic equation in an either stochastic or deterministic way. © 2012 Elsevier B.V.
