Lyubeznik 引入了单项式理想的大小概念,并表明单项式理想的大小增加了其深度的下限。与此相关的是,赫尔佐格、波佩斯库和弗拉多尤表明,尺寸增加同时也是斯坦利深度的下限。事实证明,他们论文中的分裂变量技术特别适合比较无平方单项式理想的斯坦利深度和大小。在本文中,我们推广了这种技术并研究了一般单项式理想的商。作为一种应用,我们考虑各种条件下单项式理想商的斯坦利深度下界。通过亚历山大对偶性,我们还考虑了杂波边缘理想的斯坦利支持规律性的上限。与此同时,最近,Katthän 和 Seyed Fakhari 根据 lcm 数建立了深度和斯坦利深度的另一个下限。使用分裂变量技术,我们提供了其结果的替代证明。
Lyubeznik introduced the concept of size of a monomial ideal and showed that the size of a monomial ideal increased byis a lower bound for its depth. Associated with this, Herzog, Popescu and Vladoiu showed that the size increased byis simultaneously a lower bound for its Stanley depth. It turns out that the splitting-variables technique in their paper is particularly suited for comparing the Stanley depth and size of squarefree monomial ideals. In this paper, we generalize this technique and investigate the quotientwhenare general monomial ideals. As an application, we consider lower bounds for Stanley depth of quotients of monomial ideals under various conditions. Through Alexander duality, we also consider upper bounds for the Stanley support-regularity of edge ideals of clutters. Meanwhile, recently, Katthän and Seyed Fakhari established another lower bound for depth and Stanley depth ofin terms of the lcm number. Using the splitting-variables technique, we provide an alternate proof of their result.
