Abstract:
Let _{} be a real reflexive Banach space with a uniformly Gâteaux differentiable norm, _{} be a nonempty bounded closed convex subset of _{} i=1,2,...,r be a finite family of asymptotically nonexpansive mappings such that for each _{} Let _{ } be a nonempty set of common fixed points of _{} and define
_{} . Let _{} be fixed and let _{} be such that _{} as _{} . We can prove that the sequence _{} satisfying the relation_{} associated with _{} , converges strongly to a fixed point of _{} provided _{} possesses uniform normal structure. Furthermore we prove that the iterative process: _{} _{}
_{} , converges strongly to a fixed point of _{}

Abstract:
We have studied Regularization of Hammerstein's Type Operator Equations in general Banach Spaces. In this paper, the results have been employed to establish regularized solutions to Hammerstein's type operator equations in Hilbert spaces by looking at three cases of regularization.
