| Abstract: | Some multiplicity results of solutions are obtained for a class of elliptic systems which are near resonance with a nonprincipal eigenvalue by the classical saddle point theorem and a local saddle point theorem in critical point theory. |
| Keywords: | Elliptic systems Near resonance Saddle point theorem Nonprincipal eigenvalue |
