Contractive mapping theorems in Partially ordered metric spaces

open access: yesCubo, 2020
The purpose of this paper is to establish some coincidence, common fixed point theorems for monotone $f$-non decreasing self mappings satisfying certain rational type contraction in the context of a metric spaces endowed with partial order.

Solving Integral Equations Using Weakly Compatible Mappings via D*-Metric Spaces

open access: yesAxioms, 2022
We introduce a new pair of mappings (S,T) on D*-metric spaces called DS*-W.C. and DRS*-W.C. Many examples are presented to show the difference between these mappings and other types of mappings in the literature.

COINCIDENCE POINTS OF WEAKLY COMPATIBLE MAPPINGS [PDF]

open access: yesBulletin of the Korean Mathematical Society, 2008
We present coincidence points and common fixed point re- sults for (f, g)-contractive mapping and (f, g)-nonexpansive mappings. Our results generalize and complement various known results existing in the literature.

Common Fixed Point of (ψ, β, L)-Generalized Contractive Mapping in Partially Ordered b-Metric Spaces

open access: yesAxioms, 2023
The purpose of this paper is to attain the existence of coincidences and common fixed points in four mappings satisfying (ψ,β,L)-generalized contractive conditions in the framework of partially ordered b-metric spaces.

Some Common Fixed Point Theorems in Generalized Metric Spaces

open access: yesJournal of Mathematics, 2013
First we prove common fixed point theorems for weakly compatible maps which generalize the results of Chen (2012). Secondly, we prove common fixed point theorems using property E.A. along with weakly compatible maps.

Some Common Fixed Points Theorems of Four Weakly Compatible Mappings in Metric Spaces

open access: yesمجلة بغداد للعلوم, 2021
In this paper, we proved coincidence points theorems for two pairs mappings which are defined on nonempty subset   in metric spaces by using condition (1.1). As application, we established a unique common fixed points theorems for these mappings by using

Viability of bi-maximal solution of the Zee mass matrix [PDF]

open access: yes, 2001
We know $L_e-L_\mu-L_\tau$ symmetry gives $m^2_1= m^2_2 >> m^2_3$ pattern in Zee model. $\Delta m^2_\odot$ emerges from a small breaking of this symmetry.

Some Results of Common Fixed Point for Compatible Mappings in Ƒ-Metric Spaces

open access: yesJournal of New Theory, 2021
Recently, Ƒ-metric space has been started, and a natural topology has been described in these spaces by Jleli and Samet. Furthermore, a new form of the Banach contraction principle has been given in the new spaces.

The contact process in heterogeneous and weakly-disordered systems [PDF]

open access: yes, 2006
The critical behavior of the contact process (CP) in heterogeneous periodic and weakly-disordered environments is investigated using the supercritical series expansion and Monte Carlo (MC) simulations. Phase-separation lines and critical exponents $\beta$

A Unique Common Fixed Point for an Infinity of Set-Valued Maps

open access: yesAnnales Mathematicae Silesianae, 2018
The main purpose of this paper is to establish some common fixed point theorems for single and set-valued maps in complete metric spaces, under contractive conditions by using minimal type commutativity and without continuity.
