Coincidence points in uniform spaces [PDF]

International Journal of Mathematics and Mathematical Sciences, 1992
Summary: We give a coincidence point theorem in sequentially complete Hausdorff uniform spaces. Our result reduces to a result of \textit{S. P. Acharya} [Yokohama Math. J. 22, 105-116 (1974; Zbl 0295.54058)].

Coincidence Points in Generalized Metric Spaces

Set-Valued and Variational Analysis, 2014
The authors continue the research (see [\textit{A. V. Arutyunov}, Dokl. Math. 76, No. 2, 665--668 (2007; Zbl 1152.54351); translation from Dokl. Akad. Nauk, Ross. Akad. Nauk 416, No. 2, 151--155 (2007)]) on coincidence points for maps (single-valued and set-valued) such that one of them is \(\beta\)-Lipschitz continuous and the second one is an ...

On almost coincidence points in generalized convex spaces

Fixed Point Theory and Applications, 2006
We prove an almost coincidence point theorem in generalized convex spaces. As an application, we derive a result on the existence of a maximal element and an almost coincidence point theorem in hyperconvex spaces.

Continuous Dependence of Coincidence Points on a Parameter

Set-Valued and Variational Analysis, 2014
In the paper, the authors consider the coincidence points existence problem with a parameter in metric spaces. They give sufficient conditions for the dependence of a coincidence point on the parameter to be continuous, Hölder continuous, or Lipschitz continuous.

Coincidence Points of Weaker Contractions in Partially Ordered Metric Spaces

Journal of Applied Mathematics, 2013
We prove new coincidence point theorems for the -contractions and generalized Meir-Keeler-type --contractions in partially ordered metric spaces. Our results generalize many recent coincidence point theorems in the literature.

Tracking Health Related Quality of Life From Diagnosis to Follow‐Up Among Australian Children With Acute Lymphoblastic Leukaemia

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Acute lymphoblastic leukaemia (ALL) is one of the most treatable forms of paediatric cancer; however, there is a substantial burden of treatment‐related toxicities (TRTs). In addition, the long‐term changes in children's health‐related quality of life (HRQoL) due to toxic treatments are not well understood.

On Approximate Coincidence Point Properties and Their Applications to Fixed Point Theory

Journal of Applied Mathematics, 2012
We first establish some existence results concerning approximate coincidence point properties and approximate fixed point properties for various types of nonlinear contractive maps in the setting of cone metric spaces and general metric spaces.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Some Coincidence and Common Fixed Point Results in Fuzzy Metric Space with an Application to Differential Equations

Journal of Function Spaces, 2021
In this paper, we study some coincidence point and common fixed point theorems in fuzzy metric spaces by using three-self-mappings. We prove the uniqueness of some coincidence point and common fixed point results by using the weak compatibility of three ...

Some results on coincidence points [PDF]

Bulletin of the Australian Mathematical Society, 1999
In this paper we prove some coincidence point theorems for nonself single-valued and multivalued maps satisfying a nonexpansive condition. These extend fixed point theorems for multivalued maps of a number of authors.
