A Nadler-type fixed point theorem in dislocated spaces and applications
, 2018 In this paper, we introduce the concept of a Hausdorff dislocated metric . We initiate the study of fixed point theory for multi-valued mappings on dislocated metric space using the Hausdorff dislocated metric and we prove a generalization of the well ...

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.

Compactification of a map which is mapped to itself [PDF]
, 2002 We prove that if $T: X \to X$ is a selfmap of a set $X$ such that $\bigcap \{T^{n}X: n\in N}\}$ is a one-point set, then the set $X$ can be endowed with a compact Hausdorff topology so that $T$ is continuous.Comment: 5 ...

Solving Periodic Boundary Value Problem via Product Type Rational Contractions
International Journal of Mathematics and Mathematical Sciences, Volume 2024, Issue 1, 2024.In this paper, we define some new product types of rational contractions for single‐valued mappings in generalized metric spaces. We prove the uniqueness of fixed point (FP) and common fixed point (CFP) theorems under the new product types of rational contractions in generalized metric spaces with the application of boundary value problem.

Dislocated metric space to metric spaces with some fixed point theorems
, 2013 In this paper, we notice the notions metric-like space and dislocated metric space are exactly the same. After this historical remark, we discuss the existence and uniqueness of a fixed point of a cyclic mapping in the context of metric-like spaces.

Common fixed points of almost generalized (ψ,φ)s-contractive mappings in ordered b-metric spaces
, 2013 In this paper, we introduce the notion of almost generalized (ψ,φ)s-contractive mappings and we establish some fixed and common fixed point results for this class of mappings in ordered complete b-metric spaces.

Discussion on some coupled fixed point theorems
, 2013 In this paper, we show that, unexpectedly, most of the coupled fixed point theorems (on ordered metric spaces) are in fact immediate consequences of well-known fixed point theorems in the literature.MSC: 47H10, 54H25.

Fixed Point Theorems in Complex Valued Extended b-Metric Spaces
Moroccan Journal of Pure and Applied Analysis, 2019 In this article, inspired by the concepts of extended b-metric spaces, we introduce the notion of complex valued extended b-metric spaces. Using this new idea, some fixed point theorems involving rational contractive inequalities are proved.
