Modified Noor iterations for nonlinear equations in Banach spaces

摘要

The purpose of this paper is to analyze the modified three-step iterative scheme for solving nonlinear operator equations in real Banach spaces. Our results can be viewed as an extension of three-step and two-step iterative schemes of Glowinski and Le Tallec [R. Glowinski, P. Le Tallec, Augemented Lagrangian and Operator-Splitting Methods in Nonlinear Mechanics, SIAM Publishing Co., Philadelphia, 1989] Noor [M.A. Noor, Three-step iterative algorithms for multivalued quasi variational inclusions, J.
