Fixed Point for Partial Metric Spaces [PDF]

ISRN Applied Mathematics, 2011
We consider the partial metric on a set X, define ϵ-fixed point for maps, and obtain some sufficient and necessary conditions on that, also we obtain some sufficient and necessary theorems on ϵ-fixed point.

T_0 functional Alexandroff topologies are partial metrizable

Applied General Topology
If f : X → X is a function, the associated functional Alexandroff topology on X is the topology whose closed sets are { A ⊆ X : f ( A ) ⊆ A } . We prove that every functional Alexandroff topology is pseudopartial metrizable and every T0 functional ...

Common fixed point of a power graphic (F,psi)-contraction pair on partial b-metric spaces with application

Nonlinear Analysis, 2017
The aim of this paper is to inaugurate power graphic (F,ψ)-contraction pair and to establish fixed point results for such mappings defined on partial b-metric spaces endowed with a graph.

Weak Partial b-Metric Spaces and Nadler’s Theorem

Mathematics, 2019
The purpose of this paper is to define the notions of weak partial b-metric spaces and weak partial Hausdorff b-metric spaces along with the topology of weak partial b-metric space. Moreover, we present a generalization of Nadler’s theorem by using

Partial Order Infinitary Term Rewriting [PDF]

Logical Methods in Computer Science, 2014
We study an alternative model of infinitary term rewriting. Instead of a metric on terms, a partial order on partial terms is employed to formalise convergence of reductions.

BEBERAPA SIFAT PEMETAAN C-KONTRAKTIF DI RUANG METRIK PARSIAL DAN TITIK TETAPNYA

E-Jurnal Matematika
Partial metric space is a generalization of ordinary metric space, in partial metric space the axiom d(x,x) is no longer necessarily zero. Partial metric space was first introduced in 1994, since then many researchers have continued to learn about ...

Common Fixed Points in a Partially Ordered Partial Metric Space [PDF]

International Journal of Analysis, 2013
In the first part of this paper, we prove some generalized versions of the result of Matthews in (Matthews, 1994) using different types of conditions in partially ordered partial metric spaces for dominated self-mappings or in partial metric spaces for self-mappings.

On Statistical Convergence of Order α in Partial Cone Metric Spaces

Mathematics
The importance of sequence spaces has increased with the emergence of various new convergence methods such as statistical convergence. On the other hand, partial metric spaces hold an important place in computer science, data science, and convergence ...

A Suzuki type unique common fixed point theorem for two pairs of hybrid maps under a new condition in partial metric spaces

Demonstratio Mathematica, 2016
In this paper, we introduce a new condition namely: condition (W.C.C.) and utilize the same to prove a Suzuki type unique common fixed point theorem for two hybrid pairs of mappings in partial metric spaces employing the partial Hausdorff metric which ...

Partial Metrics Viewed as w-Distances: Extending Some Powerful Fixed-Point Theorems

Mathematics
Involving w-distances and hybrid contractions that combine conditions of the Ćirić type and Samet et al. type, we obtain some general fixed-point results for quasi-metric spaces from which powerful and significant fixed-point theorems on partial metric ...
