General Common Fixed Point Theorems and Applications [PDF]

open access: yesJournal 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.

Common fixed point theorems for compatible mappings [PDF]

open access: yesInternational 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.

Generalized Common Fixed Point Results with Applications [PDF]

open access: yesAbstract and Applied Analysis, 2014
We obtained some generalized common fixed point results in the context of complex valued metric spaces. Moreover, we proved an existence theorem for the common solution for two Urysohn integral equations. Examples are presented to support our results.

Common Fixed Points of Commuting Mappings [PDF]

open access: yesProceedings 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

On Characterizations of Fixed and Common Fixed Points

open access: yesJournal 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.

On common fixed point theorems [PDF]

open access: yesBulletin 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.

open access: yesProceedings of the American Mathematical Society, 1979

Results on common fixed points [PDF]

open access: yesInternational 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).

Common fixed point theorems and applications

open access: yesInternational 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
