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.

On the structure of the set of coincidence points
Sbornik: Mathematics, 2015 We consider the set of coincidence points for two maps between metric spaces. Cardinality, metric and topological properties of the coincidence set are studied. We obtain conditions which guarantee that this set (a) consists of at least two points; (b) consists of at least n points; (c) contains a countable subset; (d) is uncountable.

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.

On Changing Fixed Points and Coincidences to Roots [PDF]
Proceedings of the American Mathematical Society, 1992 The coincidence problem, finding solutions to f ( x ) = g ( x ) f(x) = g(x) , can sometimes be converted to a root problem, finding solutions to σ ( x ) = a \sigma (x) = a .

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.

NONLINEAR CONDITIONS FOR COINCIDENCE POINT AND FIXED POINT THEOREMS [PDF]
Taiwanese Journal of Mathematics, 2012 In this paper, we first establish some new types of fixed point theorem which generalize and improve Berinde-Berinde's fixed point theorem, Mizoguchi-Takahashi's fixed point theorem and many results in [W.-S. Du, Some new results and generalizations in metric fixed point theory, Nonlinear Anal. 73 (2010), 1439-1446] and references therein.

Coincidence point theorems for multivalued mappings [PDF]
International Journal of Mathematics and Mathematical Sciences, 1991 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].

Nothing but coincidences: the point-coincidence and Einstein’s struggle with the meaning of coordinates in physics [PDF]
European Journal for Philosophy of Science, 2021 AbstractIn his 1916 review paper on general relativity, Einstein made the often-quoted oracular remark that all physical measurements amount to a determination of coincidences, like the coincidence of a pointer with a mark on a scale. This argument, which was meant to express the requirement of general covariance, immediately gained great resonance ...
