Coupled Coincidence Points of Mappings in Ordered Partial Metric Spaces

Abstract and Applied Analysis, 2012
New coupled coincidence point and coupled fixed point results in ordered partial metric spaces under the contractive conditions of Geraghty, Rakotch, and Branciari types are obtained. Examples show that these results are distinct from the known ones.

Existence of a common solution for a system of nonlinear integral equations via fixed point methods in b-metric spaces

Open Mathematics, 2016
In this paper we introduce a property and use this property to prove some common fixed point theorems in b-metric space. We also give some fixed point results on b-metric spaces endowed with an arbitrary binary relation which can be regarded as ...

Brainstem and Cerebellar Volume Loss and Associated Clinical Features in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Introduction Progressive Supranuclear Palsy (PSP) is a neurodegenerative ‘tauopathy’ with predominating pathology in the basal ganglia and midbrain. Caudal tau spread frequently implicates the cerebellum; however, the pattern of atrophy remains equivocal.

On coincidence and common fixed points of nearly densifying mappings

International Journal of Mathematics and Mathematical Sciences, 2000
Coincidence and common fixed point theorems for certain new classes of nearly densifying mappings are established. Our results extend, improve, and unify a lot of previously known theorems.

Non-Expansive Multi-Valued Mappings and Convexity in Fuzzy Metric Space [PDF]

Sahand Communications in Mathematical Analysis
In this article, we delve into the concept of convexity within fuzzy metric spaces and delve into their structural characteristics. We present several theorems concerning the existence of coincidence points in fuzzy convex metric spaces.

Coincidence between the distribution of myofascial trigger points and the presence of blood vessels in the gastrocnemius muscle: Implications for invasive procedures [PDF]

Purpose The gastrocnemius venous system presents different anatomical variants. There have been described four locations of myofascial trigger points (MTrPs) in this muscle.

Coincidence points of generalized multivalued (f, L)-almost F-contraction with applications [PDF]

, 2015
Recently Abbas [M. Abbas, Coincidence points of multivalued f−almost nonexpansive mappings, Fixed Point Theory, 13 (1) (2012), 3–10] introduced the concept of f−almost contraction which generalizes the class of multivalued almost contraction mapping ...

A note on noncompact collectively coincidence point theory

Periodica Mathematica Hungarica, 2023
AbstractIn this paper we present a variety of collectively fixed point and coincidence point results where the maps are not necessarily compact. Our arguments are based on a very general fixed point result in the literature.
