Abstract

In this paper, we study some algebraic invariants of [Formula: see text]-spread ideals, [Formula: see text], such as the projective dimension and the Castelnuovo–Mumford regularity, by means of well-known graded resolutions. We state upper bounds for these invariants and, furthermore, we identify a special class of [Formula: see text]-spread ideals for which such bounds are optimal.
t-扩散理想的射影维数和Castelnuovo-Mumford正则性
本文利用著名的分级分解方法,研究了[公式:见文]-扩散理想,[公式:见文]的一些代数不变量,如射影维数和Castelnuovo-Mumford正则。我们给出了这些不变量的上界,进一步,我们确定了一类特殊的[公式:见文本]-扩展理想,对于这些理想,上界是最优的。
