The Self-similar Solution for Ginzburg-Landau Equation and Its Limit Behavior in Besov Spaces

In this paper, we study the limit behavior of self-similar solutions for the Complex Ginzburg-Landau (CGL) equation in the nonstandard function space E_{s,p}.

Moreover we show that the self-similar solutions of CGL equation converge, globally in time, to those of its limit equation as the parameters tend to zero.
