## Common fixed points of quasi-contractive operators.(English)Zbl 1235.47073

Summary: We establish a general theorem to approximate common fixed points of quasi-contractive operators on a normed space through the modified Ishikawa iteration process with errors in the sense of L.-S. Liu [J. Math. Anal. Appl. 194, No. 1, 114–125 (1995; Zbl 0872.47031)]. Our result generalizes and improves upon, among others, the corresponding result of V. Berinde [Acta Math. Univ. Comen., New Ser. 73, No. 1, 119–126 (2004; Zbl 1100.47054)].
