We establish a sufficient as well as a local convergence theorem. We also provide the best possible practical error bound for this method. 展开更多

We provide convergence results and error estimates for Newton-like methods in generalized Banach spaces.The idea of a generalized norm is used whichis defined to be a map from a linear space into a partially ordered Banach space.Convergence results and error estimates are improved compared with the real norm theory. 展开更多

ON THE METHOD OF TANGENT HYPERBOLAS

In this study we provide new convergence theorems for the method of tangent hyperbolas under standard Newton kantorovich-type assumptions. We also show how to improve on the results obtained by Safiev, Ya-mamoto and K... In this study we provide new convergence theorems for the method of tangent hyperbolas under standard Newton kantorovich-type assumptions. We also show how to improve on the results obtained by Safiev, Ya-mamoto and Kanno. 展开更多
