Abstract:Let K be a nonempty closed convex subset of a real Banach space E and let View the MathML source be a uniformly continuous pseudocontraction. Fix any uK. Let {xn} be defined by the iterative process: x0K, xn+1:=μn(αnTxn+(1−αn)xn)+(1−μn)u. Let δ(?) denote the modulus of continuity of T with pseudo-inverse ?. If View the MathML source and {xn} are bounded then, under some mild conditions on the sequences n{αn} and n{μn}, the strong convergence of {xn} to a fixed point of T is proved. In the special case where T is Lipschitz, it is shown that the boundedness assumptions on View the MathML source and {xn} can be dispensed with.
