In this paper, by using sub-super solutions method, we study the existence of weak positive solution of Kirrchoff hyperbolic systems in bounded domains with multiple parameters. These results extend and improve many results in the literature

Abstract. In this paper, a new version of Ekeland's variational principle on partial metric spaces is given. Using this variational principle, we establish a general result on the existence of a fixed point for a class of genralized set-valued contractions on partial metric spaces, other results are also given.
