A new iterative method for common fixed points of a finite family of nonexpansive mappings
Let X be a real uniformly convex Banach space and C a closed convex nonempty subset of X. Let {Ti}i=1r be a finite family of nonexpansive self-mappings of C. For a given x1 ∈ C, let {xn} and {xn(i)}, i = 1,2,.., r, be sequences defined xn(0) = xn, xn(i) = an1(1)T1xn(0) + (1 - an1(1)xn(0), xn(2) = an...

| Summary: | Let X be a real uniformly convex Banach space and C a closed convex nonempty subset of X. Let {Ti}i=1r be a finite family of nonexpansive self-mappings of C. For a given x1 ∈ C, let {xn} and {xn(i)}, i = 1,2,.., r, be sequences defined xn(0) = xn, xn(i) = an1(1)T1xn(0) + (1 - an1(1)xn(0), xn(2) = an2(2) T2xn(1) + an1(2) T1xn + (1 - an2(2) - an1(2))xn,..;, xn+1 = xn(r) - anr(r) Trxn(r-1) + an(r-1)(r) Tr-1xn(r-2) +..; + an1(r)T1xn + (1 - an(r)(r) - an(r-1)(r) -..; - an1(r)xn, n ≥ 1, where ani(j) ∈ (0, 1) for all j ∈ {1, 2,..,r}, n ∈ N and i = 1, 2,..;, j. In this paper, weak and strong convergence theorems of the sequence {xn} to a common fixed point of a finite family of nonexpansive mappings Ti (i = 1, 2,..;, r) are established under some certain control conditions. |
