On the asymptotic behaviour of the characteristics in the codiffusion of radioactive isotopes with general initial data

Abstract
The large-time behaviour of the solution of a hyperbolic-
parabolic problem in an isolated domain, which models the diffusion of
n species of radiative isotopes of the same element, is studied, assuming
general hypotheses on the initial data.
Depending on the radiative law and on the distribution of the initial
concentration, either a uniform distribution for the concentration of
each isotope or the presence of oscillations may be possible when t → ∞.
