Upper bounds for Extremal Betti Numbers of $t$-Spread Strongly Stable Ideals

Commutative Algebra 2021-02-16 v1

Abstract

We study the extremal Betti numbers of the class of tt--spread strongly stable ideals. More precisely, we determine the maximal number of admissible extremal Betti numbers for such ideals, and thereby we generalize the known results for t{1,2}t\in \{1,2\}.
