Abstract This note presents ad-nonprojection method for approximation to infinite-dimensional Moore-Penrose inverse, which includes generalized projection method as a special case. The main result (Theorem 4) gives characteristics of perfect convergence, weak perfect convergence, and uniform perfect convergence of ad-nonprojection method. This result is a generalization of several fundamental theorems known.

无限维Moore-Penrose逆的稳定逼近的Ad-Nonprojection方法

摘要 本笔记介绍了逼近无限维摩尔-彭罗斯逆的非投影方法，其中包括作为特例的广义投影方法。主要结果（定理4）给出了ad-nonprojection方法的完全收敛、弱完全收敛和均匀完全收敛的特点。这个结果是几个已知基本定理的概括。
