The Cauchy-Lorentz and Gaussian distribution in the base of this background used to obtain the probability of the neutrino oscillations. Finally, we pay attention to the case of associated incoherence damping coefficient of oscillation between flavors. http://pubs.sciepub.com/ijp/2/2/2/ijp-2-2-2.pdf neutrino oscillations four-dimensional foam Friedmann-Robertson-Walker metric
