Abstract:We consider an auxiliary operator, defined in a real Hilbert space in terms of and , that is, monotone and Lipschitz mappings (resp., monotone and bounded mappings). We use an explicit iterative process that converges strongly to a solution of equation of Hammerstein type. Furthermore, our results improve related results in the literature.
“…It is known that (J E +t 0 F ) and (J E * +t 0 K) are bijections (see e.g, Chuang [17]). It can be easily verified that if E is a smooth, strictly convex and reflexive Banach space and F : E → E * is a monotone mapping with R(J E + tF ) = E * , then for each t > 0, the resolvent J E t of F defined by…”
Equations of Hammerstein type cover large variety of areas and are of much interest to a wide audience due to the fact that they have applications in numerous areas. Suitable conditions are imposed to obtain a strong convergence result for nonlinear integral equations of Hammerstein type with monotone type mappings. A technique which does not involve the assumption of existence of a real constant whose calculation is unclear has been used in this study to obtain the strong convergence result. Moreover, our technique is applied to show the forced oscillations of finite amplitude of a pendulum as a specific example of nonlinear integral equations of Hammerstein type. Numerical example is given for the illustration of the convergence of the sequences of iteration. These are done to demonstrate to our readers that this approach can be applied to problems arising in physical systems.

“…Mustafa Nader gave conditions that ensure the existence and the uniqueness of the solution for equation (1) in the space [4]. Authors in [5][6][7][8] found sequences converged to the exact solution of equation 1under such assumptions.…”
In this paper we use the fixed-point theorem of Latrach, Taoudi and Zeghal under some conditions to find a solution for Volterra_Hammerstein integral equation in the Banach space (,-). We use this fixed point theorem with new assumptions.
