Common fixed point theorems and applications [PDF]
International Journal of Mathematics and Mathematical Sciences, 1997 The purpose of this paper is to discuss the existence of common fixed points for mappings in general quasi-metric spaces. As applications, some common fixed point theorems for mappings in probabilistic quasi-metric spaces are given. The results presented

Common fixed point theorems for compatible mappings [PDF]
International Journal of Mathematics and Mathematical Sciences, 1996 By using a compatibility condition due to Jungck we establish some common fixed point theorems for four mappings on complete and compact metric spaces These results also generalize a theorem of Sharma and Sahu.

Publicationes Mathematicae Debrecen, 2022 The following interesting theorem, extending several earlier known results, is proved. Let S and T be commuting self-maps of the complete metric space (X,d) satisfying the inequality \[ d(Sx,Ty)\leq c \max \{d(x,y),d(x,Sx),d(y,Ty),d(x,Ty),d(y,Sx\quad)\} \] for all x,y\(\in X\), where ...

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).

On common fixed point theorems [PDF]
Bulletin of the Australian Mathematical Society, 1977 The aim of this paper is to extend a recent result of S.A. Husain and V.M. Sehgal [Bull. Austral. Math. Soc. 13 (1975), 261–267]. The condition that the function should be continuous in Husain and Sehgal, op. cit., is replaced by a semicontinuity condition.

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.

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

An Application to Fixed-Point Results in Tricomplex-Valued Metric Spaces Using Control Functions
Mathematics, 2022 In the present work, we establish fixed-point results for a pair of mappings satisfying some contractive conditions on rational expressions with coefficients as point-dependent control functions in the setting of tricomplex-valued metric spaces.

Common Fixed Point Results on Complex-Valued $S$-Metric Spaces [PDF]
Sahand Communications in Mathematical Analysis, 2020 Banach's contraction principle has been improved and extensively studied on several generalized metric spaces. Recently, complex-valued $S$-metric spaces have been introduced and studied for this purpose.
