摘要

研究了经典局部上同的重要推广——Tate局部上同和Gorenstein局部上同理论。已经发现它们具有这样的消失性质和长精确序列。然而,对于局部同调,对偶呢?本文讨论了Tate局部同调和Gorenstein局部同调。本文第一部分将局部同调推广为Tate局部同调,并研究了Tate局部同调模的消失性、收敛性和某些精确序列。我们发现,对于具有有限Gorenstein投影维数的任意R模M和有限生成的任意R模N, M和N关于理想I的Tate局部同调模也是任意模。在论文的第二部分,我们将Gorenstein局部同调模作为Gorenstein版本来考虑。讨论了Gorenstein局部同调模的消失性质和一些精确序列,得到了一个连接Gorenstein、Tate和广义局部同调的精确序列。最后,作为连接这些局部同调模的精确序列的一个应用,我们发现对于分别具有有限投影维数和允许Gorenstein投影适当分辨的有限生成R -模,在某些情况下,Gorenstein局部同调与广义局部同调重合。

A Study of Some Generalizations of Local Homology
: Tate local cohomology and Gorenstein local cohomology theory, which are important generalizations of the classical local cohomology, has been investigated. It has been found that they have such vanishing properties and long exact sequences. However, for local homology, what about the duality? In this paper we are concerned with Tate local homology and Gorenstein local homology. In the first part of the paper we generalize local homology as Tate local homology, and study such vanishing properties, artinianness and some exact sequence of Tate local homology modules. We find that for an artianian R -module M and a finitely generated R -module N with finite Gorenstein projective dimension, the Tate local homology module of M and N with respect to an ideal I is also an artinian module. In the second part of the paper we consider Gorenstein local homology modules as Gorenstein version. We discuss vanishing properties and some exact sequences of Gorenstein local homology modules and obtain an exact sequence connecting Gorenstein, Tate and generalized local homology. Finally, as an applicaton of the exact sequence connecting these local homology modules, we find that for finitely generated R -modules with finite projective dimension and admitting Gorenstein projective proper resolution respectively, Gorenstein local homology coincides with generalized local homology in certain cases.
