Common Coincidence Points and Common Fixed Points in Fuzzy Semi-Metric Spaces [PDF]
Mathematics, 2018 We propose the so-called fuzzy semi-metric space in which the symmetric condition is not assumed to be satisfied. In this case, there are four kinds of triangle inequalities that should be considered.

Compatible mappings and common fixed points [PDF]
International Journal of Mathematics and Mathematical Sciences, 1986 A generalization of the commuting mapping concept is introduced. Properties of this weakened commutativity are derived and used to obtain results which generalize a theorem by Park and Bae, a theorem by Hadzic, and others.

Results on common fixed points [PDF]
International Journal of Mathematics and Mathematical Sciences, 2001 We establish common fixed point theorems related with families of self mappings on metric spaces. Our results extend, improve, and unify the results due to Fisher (1977, 1978, 1979, 1981, 1984), Jungck (1988), and Ohta and Nikaido (1994).

Unique Common Fixed Points for Expansive Maps
International Journal of Mathematics and Mathematical Sciences, 2023 In this work, we establish three common fixed point results for expansive maps satisfying implicit relations in metric and dislocated metric spaces. We do this by utilizing recently developed concept of occasionally weakly biased maps of type A.

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 under strict conditions [PDF]
Mathematica Moravica, 2020 In this contribution, three new concepts called reciprocally continuous, strictly subweakly compatible and strictly subreciprocally continuous single and multivalued mappings are given for obtention some common fixed point theorems in a metric space. Our

Common Fixed Points of Commuting Mappings [PDF]
Proceedings of the American Mathematical Society, 1975 Let X X be a dendroid and S S an abelian semigroup of continuous monotone self-mappings of X X . A point x ϵ X x\epsilon X is fixed under S S if g ( x ) = x g(x) = x for all

Some Common Fixed Points Theorems of Four Weakly Compatible Mappings in Metric Spaces
مجلة بغداد للعلوم, 2021 In this paper, we proved coincidence points theorems for two pairs mappings which are defined on nonempty subset in metric spaces by using condition (1.1). As application, we established a unique common fixed points theorems for these mappings by using

On Characterizations of Fixed and Common Fixed Points
Journal of Mathematical Analysis and Applications, 1998 The authors introduce the concept of \(L\)-mapping which is equivalent to the concept of \(C\)-mapping introduced by \textit{S. Zhang} [Proc. Am. Math. Soc. 97, 343-346 (1986; Zbl 0593.54045)] and establish criteria for the existence of fixed points of \(L\)-mappings.
