Authors’ abstract: “Let \(T\) be an asymptotically pseudocontractive self-mapping of a nonempty closed convex subset \(D\) of a reflexive Banach space \(X\) with a Gâteaux differentiable norm. We deal with the problem of strong convergence of almost fixed points \(x_n=\mu_n T^n x_n+(1-\mu_n)u\) to a fixed point of \(T\). Next, this result is applied to deal with the strong convergence of the explicit iteration process \(z_{n+1}(\alpha_n T^n z_n+ (1-\alpha_n)z_n)+ (1-v_{n+1})u\) to a fixed point of \(T\).”
