A coupled common fixed point theorem for a family of mappings
Nonlinear Analysis, 2013 In this paper we introduce the concept of coincidentally commuting pair in the context of coupled fixed point problems. It is established that an arbitrary family of mappings has a coupled common fixed point with two other functions under certain ...

Compatible mappings and common fixed points
International Journal of Mathematics and Mathematical Sciences, 1986 A generalization of the commuting mapping concept is introduced. Properties of this weakened commutativity are derived and used to obtain results which generalize a theorem by Park and Bae, a theorem by Hadzic, and others.

FIXED POINT THEOREMS FOR COMMUTING MAPPINGS
Demonstratio Mathematica, 1988 The author proves theorems of the following type: Let f and g be two continuous functions on a complete metric space and T, S two multivalued functions on the space CB(X) of nonempty closed and bounded subsets of X. If these functions commute and fullfil some inequality there exist common fixed points.

Journal of Dental Education, EarlyView.ABSTRACT Purpose/Objectives Class attendance has traditionally been viewed as essential for academic success and professional development, particularly in health professions education. However, evolving educational technologies and changing student demographics have sparked debate about the necessity of mandatory attendance policies, especially in the ...

A note on commuting graphs for symmetric groups [PDF]
, 2009 The commuting graph C(G;X) , where G is a group and X a subset of G, has X as its vertex set with two distinct elements of X joined by an edge when they commute in G.

Commuting in multinodal urban systems: An empirical comparison of three alternative models [PDF]
The paper analyses whether the basic monocentric model of urban structure and commuting explains actual commuting in Europe, i.e. the Netherlands. As in the United States much wasteful commuting is established.

Journal of Dental Education, EarlyView.ABSTRACT Objective This study investigated the perceived stressors and resilience factors among dental hygiene (DH) students in the United States (US) and Japan. Methods A cross‐sectional survey was administered to a convenience sample of DH students from two US DH programs and one DH program in Japan.

Common fixed point theorems for weakly compatible mappings in fuzzy metric spaces
Le Matematiche, 2013 The aim of this paper is to prove a common fixed point theorem for a pair of weakly compatible mappings in fuzzy metric space by using the (CLRg) property. An example is also furnished which demonstrates the validity of our main result. As an application

Line Graphs of Multigraphs and the Forbidden Graph E 6
Journal of Graph Theory, EarlyView.ABSTRACT The line graph Γ of a multigraph Δ is the graph whose vertices are the edges of Δ, where two such edges are adjacent if and only if they meet in a single vertex of Δ. We provide several characterizations of such line graphs and in particular show that a graph is a line graph if and only if it does not contain one of the 32 graphs, all of which

Common Fixed Point Theorems for Occasionally Converse Commuting Mappings in Semi-metric Space
, 2014 In this paper, we establish a common fixed point theorem for three pairs of self mappings in semi-metric space for occasionally converse commuting maps which improves and extends similar known results in the ...
