Nonlinearities in the drift and diffusion coefficients influence temporal dependence in scalar diffusion models. We …. Les non-linéarités dans les coefficients de mouvement et de diffusion ont une incidence sur la dépendance temporelle dans … le cas des modèles de diffusion scalaire. Nous examinons ce lien en recourant à deux notions de dépendance temporelle …
