On common fixed points of compatible mappings in metric and Banach spaces
We prove a number of results concerning the existence of common fixed points of a family of maps satisfying certain contractive conditions in metric and Banach spaces.

On common fixed and periodic points of commuting functions
It is known that two commuting continuous functions on an interval need not have a common fixed point. It is not known if such two functions have a common periodic point. In this paper we first give some results in this direction.

Common Fixed Points of Weak Contractions in Cone Metric Spaces [PDF]
Results on common fixed points of mappings in cone metric spaces under weak contractive conditions (B. S. Choudhury and N. Metiya (2010)) are unified and generalized.

On a fixed point theorem of Fisher and Sessa
A fixed point theorem of Fisher and Sessa is generalized by replacing the requirements of commutativity and nonexpansiveness by compatibility and continuity respectively.

Common Fixed Points of (α,η) − (θ,ϝ) Rational Contractions with Applications
We present the notion of set valued (α,η)-(θ,ϝ) rational contraction mappings and then some common fixed point results of such mappings in the setting of metric spaces are established.

Common fixed points for Lipschitzian semigroups
Summary: \textit{T.--C.\ Lim} and \textit{H.--K.\ Xu} [Nonlinear Anal., Theory Methods Appl.\, 25, No.\,11, 1231--1235 (1995; Zbl 0845.47045)] established a fixed point theorem for uniformly Lipschitzian mappings in metric spaces with uniform normal structure. Recently, \textit{Y.--Y.\,Huang} and \textit{C.--C.\,Hong} [Int.\, J.\, Math.\, Math.\, Sci.\,

On coincidence and common fixed points of nearly densifying mappings
Coincidence and common fixed point theorems for certain new classes of nearly densifying mappings are established. Our results extend, improve, and unify a lot of previously known theorems.

Common fixed point and common coupled fixed point theorems for weakly monotone mappings
In this paper we have established two common fixed point theorems which are variants of the fixed point theorem of Boyd and Wong [On nonlinear contractions, Proc. Amer. Math. Soc. 20(1969), 458-464]. By applying the newly established fixed point theorems two common coupled fixed point theorems have been proved for a pair of weakly increasing mappings ...

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