Common Fixed Points for Multimaps in Metric Spaces [PDF]
Fixed Point Theory and Applications, 2010 We discuss the existence of common fixed points in uniformly convex metric spaces for single-valued pointwise asymptotically nonexpansive or nonexpansive mappings and multivalued nonexpansive, ∗-nonexpansive, or ε-semicontinuous maps under ...

On common fixed points, periodic points, and recurrent points of continuous functions [PDF]
International Journal of Mathematics and Mathematical Sciences, 2003 It is known that two commuting continuous functions on an interval need not have a common fixed point. However, it is not known if such two functions have a common periodic point.

Common fixed points and partial orders [PDF]
Proceedings of the American Mathematical Society, 1979 It is observed that certain theorems on common fixed points may be derived from a theorem on partially ordered sets.

Common fixed points for family of mappings
International Journal of Mathematics and Mathematical Sciences, 1984 The main aim of the present paper is to prove the existence of common fixed points for mappings which are not necessarily continuous. Our results, which are primarly motivated by investigation of Husain and Sehgal (Bull. Austral. Math. Soc.

Weak Contractions, Common Fixed Points, and Invariant Approximations [PDF]
Journal of Inequalities and Applications, 2009 The existence of common fixed points is established for the mappings, where is -weak contraction on a nonempty subset of a Banach space. As application, some results on the invariant best approximation are proved.

Multivalued Common Fixed Points Theorem in Complex b-Metric Spaces
Mathematics, 2023 In this paper, we establish a result for the existence of common fixed points for multi-valued mappings, satisfying some contractions for complex-valued b-metric spaces. Finally, we present an example to illustrate and support our results.

Common Fixed Points in Generalized Metric Spaces with a Graph
Journal of Mathematics, 2019 The aim of this paper is to prove the existence and uniqueness of points of coincidence and common fixed points for a pair of self-mappings defined on generalized metric spaces with a graph. Our results improve and extend several recent results of metric

Common Fixed Points for Nonlinear Quasi-Contractions of Ćirić Type [PDF]
Abstract and Applied Analysis, 2014 We establish common fixed points theorems for two self-mappings satisfying a nonlinear contractive condition of Ćirić type with a Q-function. Furthermore, using the scalarization method, we deduce some results of common fixed point in tvs-cone metric ...

Common Fixed Points via λ-Sequences in G-Metric Spaces
Journal of Mathematics, 2017 We use λ-sequences in this article to derive common fixed points for a family of self-mappings defined on a complete G-metric space. We imitate some existing techniques in our proofs and show that the tools employed can be used at a larger scale.

Stability of common fixed points in uniform spaces [PDF]
Fixed Point Theory and Applications, 2011 Stability results for a pair of sequences of mappings and their common fixed points in a Hausdorff uniform space using certain new notions of convergence are proved. The results obtained herein extend and unify several known results.
