On Chidume’s Open Questions and Approximate Solutions of Multivalued Strongly Accretive Mapping Equations in Banach Spaces

Some new convergence theorems of the Ishikawa iteration process for multivalued pseudo-contractive mappings and multi-valued accretive mappings are obtained, which affirmatively answer the open questions put forth by C. E. Chidume Proc. Amer. Math. Soc. 99, 1987, 283]288; 120, 1994, 545]551..
