Upper bounds for Extremal Betti Numbers of $t$-Spread Strongly Stable Ideals (2102.07462v1)

Abstract: We study the extremal Betti numbers of the class of $t$--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 $t\in {1,2}$.
