交换环上一类矩阵环的导子分解

The Decomposition of a Type of Intermediate Matrix Derivation over a Commutative Ring

在含幺交换环上,将介于对角阵环和上三角矩阵环的中间矩阵环的导子表示成了标准导子的和。

In this article, the derivation of P over a commutative ring is expressed as summation of any standard derivations by making P an intermediate matrix ring between diagonal matrix ring and upper triangular matrix ring.
