| Abstract: |
| In this thesis, we consider the existence of solutions for the following mixed dispersion nonlinear Schrödinger equation △2u-β△u-λ/2△（u2）u=g(u),in RN, (1) where g : R → R is a continuous function, λ≥0, β≥0. We shall prove that (1) has multiple non-radial solutions by variational method. This paper provides a method to prove compactness for the study of the mixed dispersion nonlinear Schrödinger equation with quasilinear terms. |
