ITERATIVE APPROXIMATIONS OF FIXED-POINTS AND SOLUTIONS FOR STRONGLY ACCRETIVE AND STRONGLY PSEUDO-CONTRACTIVE MAPPINGS IN BANACH-SPACES

In this article, we prove some new convergence theorems of the Ishikaw a and Mann iteration sequences for strongly accretive and strongly pse udo-contractive mappings by using the new inequality and the new appro ximation methods. Our main results improve and extend the correspondin g results of [J. Math. Anal. Appl. 151 (1990), 453-461; Proc. Amer. Ma th. Sec. 120 (1994), 545-551; J. Math. Appl. 192 (1995), 502-518; J. M ath.
