Convergence of Newton’s method and uniqueness of the solution of equations in Banach spaces. II. (English) Zbl 1027.65078
The authors continue their work on the Newton-Kantorowitsch method for solving nonlinear equations in a Banach space. Convergence and uniqueness results are studied under the assumption that the operator’s derivative fulfills a so-called radius or center Lipschitz condition with the weak $L$ average. Part I of this work has been published by {\it X. Wang} [IMA J. Numer. Anal. 20, No. 1, 123-134 (2000; Zbl 0942.65057)]. The reader should also consult {\it X. Wang, C. Li,} and {\it M.-J. Lai} [BIT 42, 206-213 (2002; Zbl 0998.65057)].
