A-posteriori bounds for Steffensen-like methods. (English) Zbl 0615.65060
The author establishes a-priori, as well as a-posteriori, bounds for Steffensen-like methods which are used to approximately solve nonlinear operator equations in Banach spaces. He then presents two examples and compares his bounds with those previously obtained by other authors.
