Existence of Fuzzy Fixed Points and Common Fuzzy Fixed Points for
Mathematics, 2023 This article contains results of the existence of fuzzy fixed points of fuzzy mappings that satisfy certain contraction conditions using the platform of partial b-metric spaces. Some non-trivial examples are provided to authenticate the main results. The

On a Common Jungck Type Fixed Point Result in Extended Rectangular b-Metric Spaces
Axioms, 2019 In this paper, we present a Jungck type common fixed point result in extended rectangular b-metric spaces. We also give some examples and a known common fixed point theorem in extended b-metric spaces.

Common fixed points of set-valued mappings
International Journal of Mathematics and Mathematical Sciences, 2001 The main purpose of this paper is to obtain a common fixed point for a pair of set-valued mappings of Greguš type condition. Our theorem extend Diviccaro et al. (1987), Guay et al. (1982), and Negoescu (1989).

Common Fixed Points for Multimaps in Metric Spaces
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 -semicontinuous maps under different ...

General Common Fixed Point Theorems and Applications [PDF]
Journal of Applied Mathematics, 2012 The main result is a common fixed point theorem for a pair of multivalued maps on a complete metric space extending a recent result of Đorić and Lazović (2011) for a multivalued map on a metric space satisfying Ćirić‐Suzuki‐type‐generalized contraction.

Fixed points and common points for fundamentally nonexpansive mappings on banach spaces [PDF]
Journal of Hyperstructures, 2015 In this paper, we present some fixed point theorems for fundamentally nonexpansive mappings in Banach spaces and give one common fixed point theorem for a commutative family of demiclosed fundamentally nonexpansive mappings on a nonempty weakly compact ...

On common fixed points, periodic points, and recurrent points of continuous functions
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 for Suzuki-Generalized Nonexpansive Maps
Journal of Applied Mathematics, 2013 A common fixed point theorem for a pair of maps satisfying condition (C) is proved under certain conditions. We extend the well-knownDeMarr's fixed point theorem to the case of noncommuting family of maps satisfying condition (C).

Weak Contractions, Common Fixed Points, and Invariant Approximations
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.
