Abstract:Let K be a nonempty closed convex subset of a reflexive and strictly convex Banach space E with a uniformly Gâteaux differentiable norm, and View the MathML source a nonexpansive self-mappings semigroup of K, and View the MathML source a fixed contractive mapping. The strongly convergent theorems of the following implicit and explicit viscosity iterative schemes {xn} are proved.
xn=αnf(xn)+(1−αn)T(tn)xn,
Keywords:Nonexpansive semigroup   Viscosity approximation methods   Reflexive and strictly convex Banach space   Chebyshev set
