Coincidence invariants and higher Reidemeister traces [PDF]
, 2015 The Lefschetz number and fixed point index can be thought of as two different descriptions of the same invariant. The Lefschetz number is algebraic and defined using homology.

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.

Remarks on some coupled coincidence point results in partially ordered metric spaces
Arab Journal of Mathematical Sciences, 2014 In this paper we have used a method of reducing coupled coincidence and coupled fixed point results in partially ordered metric spaces to the respective results for mappings with one variable, even obtaining (in some cases) more general theorems.

On Some Coincidence Best Proximity Point Results
Journal of Mathematics, 2021 In this paper, we discuss some (coincidence) best proximity point results for generalized proximal contractions and λ−μ-proximal Geraghty contractions in controlled metric type spaces. To clarify our study, various examples are given and some conclusions

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

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.

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 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

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.
