摘要

我们引用伯恩斯坦-格尔$'$范德-格尔$'$范德（BGG）对应关系来研究由两个著名复数--科斯祖尔（Koszul）和埃贡-诺斯考特（Eagon-Northcott）--给出的自由解析子复数。在科斯祖尔情况下，这种方法提供了子复数中自由模块等级的完整表征，而在埃贡-诺斯考特情况下，则施加了数值限制。

SUBCOMPLEXES OF CERTAIN FREE RESOLUTIONS

We invoke the Bernstein–Gel

$'$

fand–Gel

$'$

fand (BGG) correspondence to study subcomplexes of free resolutions given by two well-known complexes, the Koszul and the Eagon–Northcott. This approach provides a complete characterization of the ranks of free modules in a subcomplex in the Koszul case and imposes numerical restrictions in the Eagon–Northcott case.

期刊介绍： The Nagoya Mathematical Journal is published quarterly. Since its formation in 1950 by a group led by Tadashi Nakayama, the journal has endeavoured to publish original research papers of the highest quality and of general interest, covering a broad range of pure mathematics. The journal is owned by Foundation Nagoya Mathematical Journal, which uses the proceeds from the journal to support mathematics worldwide.
