在本文中,我们将普鲁弗 v 乘法域描述为积分域,其具有以下性质:任何线性方程组的广义解的存在性等价于系统的系数矩阵和增广矩阵的行列式理想的弱等式。事实上,我们最多获得弱全局 t 维(在 \cite{BVV87} 的意义上)的交换环的更一般结果,其中 t 是半中心遗传挠率理论。
In this paper, we characterize Prufer v-multiplication domains.as integral domains which have the property that the existence of a.generalized solution of any system of linear equations is equivalent.to a weak equality of the determinantal ideals of the coefficient.matrix and the augmented matrix of the system. In fact, we obtain a.more general result for commutative rings of weak global.t-dimension (in the sense of \cite{BVV87}) at most one, where.t is a half-centered hereditary torsion theory.
