平凡环扩张中的Gorenstein维数

Gorenstein dimensions in trivial ring extensions

Najib Mahdou, Khalid Ouarghi

摘要:

本文证明了平凡环扩张的Gorenstein整体维数往往是无穷大的。此外,我们还研究了Gorenstein性质在一个环和它的平凡环扩张之间的转移。我们的结论与一个例子表明,在一般情况下,转移的概念Gorenstein投射模不进行拉回建设。

英文摘要:

In this paper, we show that the Gorenstein global dimension of trivial ring extensions is often infinite. Also we study the transfer of Gorenstein properties between a ring and its trivial ring extensions. We conclude with an example showing that, in general, the transfer of the notion of Gorenstein projective module does not carry up to pullback constructions.
