Projective dimension and Castelnuovo-Mumford regularity of t-spread ideals

Commutative Algebra 2024-03-28 v2

Abstract

We study some algebraic invariants of tt-spread ideals, t1t\ge 1, 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 t-spread ideals for which such bounds are optimal.
