Abstract

In this paper, we consider the approximations of an iterative process for asymptotically k-strict pseudocontractive mappings in Hilbert spaces. Finally, we present some examples to study the rate of convergence.

  • In this paper, we consider the approximations of an iterative process for asymptotically k-strict pseudocontractive mappings in Hilbert spaces

  • For an asymptotically k-strict pseudocontractive type mapping T with sequence {γn}, Ceng et al proved that the Mann iteration sequence converges weakly to a fixed point of T

  • Lemma . [ ] Let B be a nonempty subset of a Hilbert space H and T : B → B be an asymptotically k-strict pseudocontractive type mapping in the intermediate sense with sequence {γn}
