Mixed monotone-generalized contractions in partially ordered probabilistic metric spaces
Fixed Point Theory and Applications, 2011 In this article, a new concept of mixed monotone-generalized contraction in partially ordered probabilistic metric spaces is introduced, and some coupled coincidence and coupled fixed point theorems are proved.

Fixed Point Theorem for Cyclic (μ, ψ, φ)-Weakly Contractions via a New Function
Annals of the West University of Timisoara: Mathematics and Computer Science, 2017 In this paper, we introduce a generalization of cyclic (μ, ψ, φ)-weakly contraction via a new function and derive the existence of fixed point for such mappings in the setup of complete metric spaces.

Open Mathematics, 2020 Consider an ordered Banach space and f,gf,g two self-operators defined on the interior of its positive cone. In this article, we prove that the equation f(X)=g(X)f(X)=g(X) has a positive solution, whenever f is strictly α\alpha -concave g-monotone or ...

Common fixed point theorem of six self-mappings in Menger spaces using (CLRST) property
Open Mathematics, 2018 In this paper, we study the existence and uniqueness of common fixed point of six self-mappings in Menger spaces by using the common limit range property (denoted by (CLRST)) of two pairs.

Open Mathematics, 2019 In this paper we introduce dislocated and dislocated quasi version of a cone b-metric space over a Banach algebra as well as weak semi α-admissible and α-identical pair of mappings and prove common fixed point theorems for a pair of α-identical and weak ...
