Kinetic approach to the asymptotic behaviour of the solution to diffusion equations
By classical arguments of kinetic theory of rarefied gases, it is proved that the fundamental solution to the heat equation gives the asymptotic representation of the solution of the Cauchy problem for the same equation. Explicit constants for the decay in relative entropy are found. The method i...
