LetT be a nonexpansive mapping on a closed convex subsetC of a real Hilbert spaceH. In the present note we deal with the weak convergence of the sequenceT n x and the sequenceS n x of the arithmetical means of the sequenceT n x, asn → ∞. We also give some results concerning the strong convergence ofS n x.
