FIXED POINTS AND COINCIDENCES IN TORUS BUNDLES [PDF]
Journal of Topology and Analysis, 2011 Minimum numbers of fixed points or of coincidence components (realized by maps in given homotopy classes) are the principal objects of study in topological fixed point and coincidence theory. In this paper, we investigate fiberwise analoga and present a general approach e.g. to the question when two maps can be deformed until they are coincidence free.

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 ...

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 \(\lim_{n\to\infty} H(fTx_n,Tfx_n)=0\).

On common fixed point of generalized contractive mappings in metric spaces [PDF]
Surveys in Mathematics and its Applications, 2012 Existence of common fixed points is established for two self-mappings satisfying a generalized contractive condition. The presented results generalize several well known comparable results in the literature. We also study well-posedness of a common fixed

Mathematics, 2019 In this paper, we introduce the concept of coincidence best proximity point for multivalued Suzuki-type α -admissible mapping using θ -contraction in b-metric space.

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 point theorems for multivalued mappings
International Journal of Mathematics and Mathematical Sciences, 1993 Some new coincidence point and fixed point theorems for multivalued mappings in complete metric space are proved. The results presented in this paper enrich and extend the corresponding results in [5-16, 20-25, 29].

Optimal Approximate Solution of Coincidence Point Equations in Fuzzy Metric Spaces
Mathematics, 2019 The purpose of this paper is to introduce α f -proximal H -contraction of the first and second kind in the setup of complete fuzzy metric space and to obtain optimal coincidence point results.
