Ss. Chang, ON CHIDUMES OPEN QUESTIONS AND APPROXIMATE SOLUTIONS OF MULTIVALUED STRONGLY ACCRETIVE MAPPING EQUATIONS IN BANACH-SPACES, Journal of mathematical analysis and applications, 216(1), 1997, pp. 94-111
Some new convergence theorems of the Ishikawa iteration process for mu
ltivalued pseudo-contractive mappings and multi-valued accretive mappi
ngs are obtained, which affirmatively answer the open questions put fo
rth by C. E. Chidume (Proc. Amer. Math. Soc. 99, 1987, 283-288; 120, 1
994, 545-551). (C) 1997 Academic Press.
