Comparing the radii of some balls appearing in connection to three local convergence theorems for Newton’s method. (English) Zbl 0907.65053

The paper is one of a series of papers by the author on Newton-like methods for nonlinear operator equations in Banach spaces.
Local convergence theorems are proven by using Lipschitz conditions on the first and second Fréchet-derivative of the nonlinear operator. In addition, the author looks for the smallest and largest region in which the starting point of the Newton-iteration has to lie in order to obtain convergence.
A possible application of the theoretical results to autonomous differential equations underlines their practical use.
