Abstract | dc.description.abstract | We consider the problem of nding a singularity of a vector eld X on a complete
Riemannian manifold. In this regard we prove a uni ed result for local convergence of
Newton's method. Inspired by previous work of Zabrejko and Nguen on Kantorovich's
majorant method, our approach relies on the introduction of an abstract one-dimensional
Newton's method obtained using an adequate Lipschitz-type radial function of the covariant
derivative of X. The main theorem gives in particular a synthetic view of several famous
results, namely the Kantorovich, Smale and Nesterov-Nemirovskii theorems. Concerning
real-analytic vector elds an application of the central result leads to improvements of some
recent developments in this area. | en_US |
