Abstract
In this paper, we prove Δ-convergence of the sequence given by the modified inexact Mann iteration
to a common fixed point of the families (T n ) and (S n ) of nonexpansive self-mappings on a closed and convex subset C of a complete CAT(0) space X, where (α n ) ⊂ [0, 1], (e n ) ⊂ ℝ+ and P is the nearest point projection on C. The strong convergence is also discussed in the exact case with certain conditions. This extends a result of Mainge.
