zero operator

In this paper, linear zero function ( LZF) of linear model and projection operator of linear space are main tools, and covariate adjustment main way.

本文以线性模型的线性零函数（LZF），线性空间的正交投影阵为工具，协方差调整为主要方法展开论述。

A new iterative scheme is introduced which is proved to be weakly convergent to zero point of maximal monotone operator A by using the techniques of Lyapunov functional, Qr operator and generalized projection operator, etc.

本文将引入新的迭代算法，并利用Lyapunov泛函，Qr算子与广义投影算子等技巧，证明了迭代序列弱收敛于极大单调算子A的零点的结论。
