摘要
本文研究Newton法的Kantorovich型定理的特点及其对Newton法的半局部收敛性研究的思想方法,论述广义Lipschitz条件下的Kantorovich型定理的概括性和统一性.同时,在理论上当x_0取定时,针对每一个满足广义Lipschitz条件的光滑算子,给出优函数的一个构造方法.
In this paper, the characteristics of Kantorovich-type theorem of Newton's method and the thoughtway on semilocal convergence properties of Newton's method are studied. The generality and the unity of Kantorovich-type theorem under the generalized Lipschitz condition are discussed. According to each smooth operator satisfying generalized Lipschitz condition when an initial guess x0 has been given, a construction method of the majorant is obtained theoretically.
