| Outline of Final Research Achievements |
Via variational approached, we study nonlinear elliptic problems. In particular, we develop a new variational approach and we construct concentrating solutions for several singular perturbation problems, where uniqueness and non-degenerary of solutions of limit problems are not known and the Lyapunov-Schmidt reduction method is not applicable.
We also introduce new variational approaches based on the scaling properties the problems, which enable us to study ground states and other solutions for several nonlinear elliptic equations and systmes.
