Tr. Further we prove that the proposed iterative algorithm converges strongly to a common fixed point of T1 T2 . Tr. Copyright 2007 Yeong-Cheng Liou et al.

Introduction Let C be a closed convex subset of a Banach space E. A mapping T of C into itself is called nonexpansive if Tx - Tyll x - yll for all X y e denote by F T the set of fixed points of T. Let T1 T2 . Tr be a finite family of nonexpansive mappings satisfying that the set F 0 1F Ti ofcommonfixed points of T1 T2 . Tr is nonempty. The problem of finding a common fixed point has been investigated by many researchers see for example Atsushiba and Takahashi 1 Bauschke 2 Lions 3 Shimizu and Takahashi 4 Takahashi et al. 5 Zeng et al. 6 . To solve this problem the iterative scheme X1 e C and Xn 1 anX1 1 - an Tnxn n e N where Tn r Tn and 0 an is used. Wittmann 7 dealt with the iterative scheme for the case r 1 see originally Halpern 8 . Bauschke 2 dealt with the iterative scheme for a finite family of nonexpansive mappings under the restriction that F F JrTr-1 T1 F T1Tr T2 F Tr-1 T1TJ. 2 Journal of Inequalities and Applications Recently Kimura et al. 9 dealt with an iteration scheme which is more general than that of Wittmann s result. They proved the following theorems. Theorem see 9 Theorem 4 . LetE be a uniformly convex Banach space whose
