INEXACT NEWTON METHODS AND NONDIFFERENTIABLE OPERATOR EQUATIONS ON BANACH SPACES WITH A CONVERGENCE STRUCTURE

         

摘要

In this study, we use inexact newton methods to find solutions of nonlinear, nondifferenti-able operator equations on Banach spaces with a convergence structure. This technique involves the introduction of a generalized norm as an operator from a linear space into a partially ordered Banach space. In this way the metric properties of the examined problem can be analyzed more precisely. Moreover , this approach allmvs us to derive from the same theorem, on the one hand, semi-local results of Kantorovich-type, and on the other hand, global results based on mono-tonicity considerations. Furthermore, ive show that special cases of our results reduce to the corresponding ones already in the literature. Finally our results are used to solve integral equations that cannot be solved with existing methods.
