Quan JO - Numerical Mathematics, a Journal of Chinese Universities VL - 4 SP - 306 EP - 311 PY - 2006 DA - 2006/11 SN - 15 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/nm/8038.html KW - AB - The purpose of this paper is to investigate some sufficient and necessary conditions for three-step Ishikawa iterative sequences with error terms for uniformly quasi-Lipschitzian mappings to converge to fixed points. Our results extend and improve the recent ones announced by Liu [3,4], Xu and Noor [5], and many others.
