We consider the large time asymptotic behavior of solutions to the initial-boundary value problema. Where n 2 N. We find large time asymptotic formulas of solutions for three different cases. These results can be foundin [56].

This work consists of five chapters and an appendix, organized from the following shape: Chapter 1 of this paper is dedicated to the introduction and begins with a recapitulation of the theory about non-linear EDPs and the ...
