The equivalence between T-stabilities of Krasnoselskij and Ishikawa iterations

Abstract

We prove the equivalence between the \(T\)-stabilities of Krasnoselskij and Ishikawa iterations; a consequence is the equivalence with the \(T\)-stability of Picard-Banach iteration.

Keywords

• Krasnoselskij iteration
• Ishikawa iteration
