Quadruple Fixed Point Theorems for Nonlinear Contractions on Partial Metric Spaces
(Univ Politecnica Valencia, Editorial Upv, 2014) Karapinar, Erdal; Tas, Kenan
The notion of coupled fixed point was introduced by Guo and Laksmikantham [12]. 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.

Fixed Point Theorem on Partial Metric Spaces Involving Rational Expressions
(Univ Miskolc inst Math, 2013) Tas, Kenan; Karapinar, Erdal; Shatanawi, Wasfi
We establish a fixed point theorem involving a rational expression in a complete partial metric space. Our result generalizes a well-known result in (usual) metric spaces. Also, we introduce an example to illustrate the usability of our result.
