摘要

利用可交换的k次幂等矩阵可同时对角化的原理与矩阵可分块的方法

对两个可交换三次幂等矩阵的非线性组合进行了研究

其组合是群可逆的

同时给出了表达式.进一步得到了三次幂等矩阵的更一般的组合形式在一定条件下是群对和矩阵的所有情形

从而将已有的三次幂等矩阵线性组合的相关结论推广到了非线性组合上.

Abstract

By using the principle of simultaneous diagonalization of two commuting k-tripotent matrices and the method of partition of matrix

the group invertibility of the nonlinear combination of two commuting tripotent matrices was mainly discussed and the formula was got.Further

all the cases that the more generalized combination of tripotent matrices was group involutory matrix were obtained under certain conditions.So the results about the linear combinations of two tripotent matrices were extended to nonlinear combinations.
