摘要
从Gorenstein同调代数的角度给出Krull整环新的阐述.应用w-算子,证明整环R是Krull的当且仅当对R的任何非零真w-理想,它w-商环的Gorenstein整体维数都为0.
In this paper,we shed new light on Krull domains from the point view of Gorenstein homological algebra.Applying the w-operation,we show that an integral domain R is Krull if and only if for any nonzero proper w-ideal I,the Gorenstein global dimension of its w-factor ring is zero.
