摘要翻译:
我们研究Gorenstein范畴。我们证明了这样一个范畴具有Tate上同调函子和连接Gorenstein相对、绝对和Tate上同调函子的Avramov-Martinkovsky精确序列。我们证明了这样一个范畴具有Hovey所说的内射模型结构,并且当范畴具有足够的投射物时,它也具有投射模型结构。作为例子,我们证明了如果X是局部Gorenstein射影格式,那么$X$上的准相干束范畴Qco(X)就是这样一个范畴,因此具有这些特征。

英文摘要:
We study Gorenstein categories. We show that such a category has Tate cohomological functors and Avramov-Martsinkovsky exact sequences connecting the Gorenstein relative, the absolute and the Tate cohomological functors. We show that such a category has what Hovey calls an injective model structure and also a projective model structure in case the category has enough projectives. As examples we show that if X is a locally Gorenstein projective scheme then the category Qco(X) of quasi-coherent sheaves on $X$ is such a category and so has these features.
