Ioana Timis . On the Weak Stability of Picard Iteration for Some Contractive Type Mappings and Coincidence Theorems. International Journal of Computer Applications. 37, 4 ( January 2012), 9-13. DOI=10.5120/4595-6549
Starting from a weak concept of stability, introduced by Berinde [1] and called “weak stability”, in [27] we develop a weaker notion, named “w²-stability”. Therefore, in this paper we prove some results of this weaker stability concept for certain class of mappings and also we give some examples of w²-stable but not weak stable nor stable iterations. Because of the restriction of an “approximate” sequence, some fixed point iteration procedures are not weakly stable so if it is used a weaker type of sequence, the stability can be obtained in the meaning of a new concept.
