In this paper, we prove the weak convergence of a modified Noor iteration for nonself I- nonexpansive mapping in a Banach space which satisfies Opial’s condition. Finally a fixed point theorem for multivalued nonexpansive mappings in a Banach space satisfying this condition is provedواژگان کلیدیOpial’s Condition, Nonexpansive Mappings, Fixed Point, Banach spaces
