Abstract

An estimation of uniqueness ball of a zero point of a mapping on Lie group is established. Furthermore, we obtain a unified estimation of radius of convergence ball of Newton’s method on Lie groups under a generalizedL-average Lipschitz condition. As applications, we get estimations of radius of convergence ball under the Kantorovich condition and theγ-condition, respectively. In particular, under theγ-condition, our results improve the corresponding results in (Li et al. 2009, Corollary 4.1) as showed in Remark 17. Finally, applications to analytical mappings are also given.
