Fixed point and coincidence point theorems

Tamkang Journal of Mathematics, 2012
In this paper, we present a generalization of some fixed point and coincidence point theorems using the notion of a on a complete metric space.Consequently, we improve and generalize various results existing in the literature.

Variation of Fixed-Point and Coincidence Sets [PDF]

Journal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1988
AbstractTopologise the set of continuous self-mappings of a Hausdorff space by the graph topology. When the set of closed subsets of the space is given the upper semi-finite topology then the function which assigns to a map its fixed-point set is continuous. In many familiar cases this is the largest such topology.

COINCIDENCE POINTS OF COMPATIBLE MULTIVALUED MAPPINGS

Demonstratio Mathematica, 1996
Let \(CB(X)\) be the space of nonempty bounded closed subsets of a metric space \((X,d)\) with the Hausdorff metric. Mappings \(T:X\to CB(X)\), \(f:X\to X\) are said to be compatible if, for any sequence \(\{x_n\}\subset X\) satisfying \(\lim_{n\to\infty} fx_n\in \lim_{n\to\infty} Tx_n\) we have \(\lim_{n\to\infty} H(fTx_n,Tfx_n)=0\).

MAPS PRESERVING THE COINCIDENCE POINTS OF OPERATORS

EURASIAN MATHEMATICAL JOURNAL, 2021
Summary: Let \(\mathcal{B(X)}\) be the algebra of all bounded linear operators on a Banach space \(\mathcal{X}\) with \(\dim \mathcal{X} \geqslant 2\). In this paper, we describe surjective maps \(\phi: \mathcal{B(X)}\to\mathcal{B(X)}\) preserving the coincidence points of operators, i.e., \(C(A,B)=C(\phi(A),\phi(B))\), for every \(A, B \in \mathcal{B ...

Weak proximal normal structure and coincidence quasi-best proximity points

Applied General Topology, 2020
We introduce the notion of pointwise cyclic-noncyclic relatively nonexpansive pairs involving orbits. We study the best proximity point problem for this class of mappings.

New fixed point theorems for fuzzy mappings via R-contraction

Arab Journal of Basic and Applied Sciences
In this manuscript, we introduce the concept of fuzzy R-contraction and establish the existence of fixed points for fuzzy mappings satisfying the fuzzy R-contraction condition.

Discussion on “Multidimensional Coincidence Points” via Recent Publications

Abstract and Applied Analysis, 2014
We show that some definitions of multidimensional coincidence points are not compatible with the mixed monotone property. Thus, some theorems reported in the recent publications (Dalal et al., 2014 and Imdad et al., 2013) have gaps. We clarify these gaps
