Later Gnana Bhaskar and Lakshmikantham in [11] investigated the coupled fixed points in the setting of partially ordered set by defining the notion of mixed monotone property. Very recently, the concept of tripled fixed point was introduced by Berinde and Borcut [7]. Following this trend, Karapmar[19] defined the quadruple fixed point. In this manuscript, quadruple fixed point is discussed and some new fixed point theorems are obtained on partial metric spaces.eninfo:eu-repo/semantics/openAccessFixed point theoremsNonlinear contractionPartial metric spacePartially ordered setQuadruple Fixed PointArticle1511124WOS:000216680700002
