Coincidence summing correction methods and influence factors of γ spectrum
He jishu, 2022 BackgroundIn the radiation environmental quality measurement or emergency measurement, one of the factors that influence the measurement results of γ spectrum activity is the cascade coincidence summing effect of multienergy nuclides.PurposeThis study ...

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.

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

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 ...

Coincidence and fixed point theorems for nonlinear hybrid generalized contractions [PDF]
, 1998 summary:In this paper we first prove some coincidence and fixed point theorems for nonlinear hybrid generalized contractions on metric spaces. Secondly, using the concept of an asymptotically regular sequence, we give some fixed point theorems for Kannan

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.

Relational Meir-Keeler Contractions and Common Fixed Point Theorems
Journal of Function Spaces, 2022 In this article, we prove some coincidence and common fixed point theorems under the relation-theoretic Meir-Keeler contractions in a metric space endowed with a locally finitely T-transitive binary relation.

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.
