| Abstract: | Existence of periodic solutions for a class of non - autonomous second order Hamihonian systems is studied. Some new existence conditions are obtained. Three new existence theorems are obtained by using the least action principle under new conditions. |

| Keywords: | periodic solutions critical point minimization |
