Marek Fila (KAMŠ):
Rate of Convergence to Separable Solutions of the Fast Diffusion Equation
Abstrakt:
We study the asymptotic behaviour near extinction of positive solutions
of the Cauchy problem for the fast diffusion equation with a subcritical exponent.
We show that separable solutions are stable in some suitable sense by
finding a class of functions which belong to their domain of attraction.
For solutions in this class we establish optimal rates of convergence to
separable solutions. This is a joint work with Michael Winkler.
