methods involving strictly pseudocontractive mappings in smooth Banach spaces. First, we
prove that the S-iteration process recently introduced by Sahu in [14] converges strongly to a
unique fixed point of a mapping T, where T is κ-strongly pseudocontractive mapping from a
nonempty, closed and convex subset C of a smooth Banach space into itself. It is also shown
that the hybrid steepest descent method converges strongly to a unique solution of a …
