Abstract We show that, under appropriate conditions, one can create a hybrid between two given iterations which can perform better…

AbstractWe prove a “collage” theorem for hemicontractive maps and we use it for inverse problems. A numerical example is given.…

AbstractWe show that the convergence of Mann, Ishikawa iterations are equivalent to the convergence of a multistep iteration, for various…

Abstract We prove the equivalence between the -stabilities of the Krasnoselskij and the Mann iterations; a consequence is the equivalence…

Abstract We prove a convergence result and a data dependence for Ishikawa iteration when applied to contraction-like operators. An example…

AbstractThe convergence of modified Mann iteration is equivalent to the convergence of modified Ishikawa iterations, when T is an asymptotically…
