Common fixed point theorems for weakly compatible pairs on cone metric spaces (Q1030603)

The results of this paper are related to those in [\textit{M. Abbas} and \textit{G. Jungck}, J. Math. Anal. Appl. 341, No.~1, 416--420 (2008; Zbl 1147.54022)], but the assumption of normality of the cone is omitted. These results also generalize some recent theorems of \textit{L.-G. Huang} and \textit{X. Zhang} [ibid. 332, No.~2, 1468--1476 (2007; Zbl 1118.54022)], \textit{P. Vetro} [Rend. Circ. Mat. Palermo (2) 56, No.~3, 464--468 (2007; Zbl 1196.54086)] and \textit{Sh. Rezapour} and \textit{R. Hamlbarani} [J. Math. Anal. Appl. 345, No.~2, 719--724 (2008; Zbl 1145.54045)].
