Involutions with fixed points in 2-Banach spaces
International Journal of Mathematics and Mathematical Sciences, 1993 Some results on fixed points of involution maps in 2-Banach spaces have been obtained. These are extensions of those proved earlier by Goebel-Zlotkiewicz, Sharma-Sharma, Assad-Sessa and Iśeki.

Common coincidence points for Nadler’s type hybrid fuzzy contractions
Journal of Inequalities and Applications, 2023 In the framework of complete metric spaces, the major objective of this paper is to investigate if a common coincidence point exists for more than two fuzzy mappings meeting the criteria of hybrid fuzzy contractions of Nadler’s type in connection with ...

An application of KKM-map principle
International Journal of Mathematics and Mathematical Sciences, 1992 The following theorem is proved and several fixed point theorems and coincidence theorems are derived as corollaries. Let C be a nonempty convex subset of a normed linear space X, f:C→X a continuous function, g:C→C continuous, onto and almost quasi ...

Central sets and substitutive dynamical systems [PDF]
, 2013 In this paper we establish a new connection between central sets and the strong coincidence conjecture for fixed points of irreducible primitive substitutions of Pisot type.

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 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.

Self-motions of pentapods with linear platform [PDF]
, 2015 We give a full classification of all pentapods with linear platform possessing a self-motion beside the trivial rotation about the platform. Recent research necessitates a contemporary and accurate re-examination of old results on this topic given by ...

Coincident-point rigidity in normed planes
Ars Mathematica Contemporanea, 2023 A bar-joint framework $(G,p)$ is the combination of a graph $G$ and a map $p$ assigning positions, in some space, to the vertices of $G$. The framework is rigid if every edge-length-preserving continuous motion of the vertices arises from an isometry of the space.
