Abstract

This paper investigates conditions under which representability of each element \(a\) from the field \(P\) as the sum \(a = f + g\) , where \({{f}^{{{{q}_{1}}}}} = f\) , \({{g}^{{{{q}_{2}}}}} = g\) , and \({{q}_{1}},{{q}_{2}}\) are fixed natural numbers >1, implies a similar representability of each square matrix over the field \(P\) . We propose a general approach to solving this problem. As an application we describe fields and commutative rings where 2 is a unit, over which each square matrix is the sum of two 4-potent matrices.

环、可表示为两个有效矩阵之和的矩阵
Abstract This paper investigates conditions under which representability of each element \(a\) from the field \(P\) as the sum \(a = f + g\) , where \({{f}^{{{{q}_{1}}}}} = f\) , \({{g}^{{{{q}_{2}}}}} = g\) , and \({{q}_{1}},{{q}_{2}}\) are fixed natural numbers >;1,意味着每个方阵在 \(P\) 域上都有类似的可表示性。我们提出了解决这个问题的一般方法。作为应用,我们描述了以 2 为单位的域和交换环,在这些域和交换环上,每个平方矩阵都是两个 4 实矩阵之和。
