Linear Resolutions and Linear Quotients in Three Variables

HoÃ i ÄÃ o, Sreehari Suresh-Babu

In this paper, we provide a combinatorial criteria for equigenerated monomial ideals in three variables to have linear resolutions. As a consequence, we prove that in three variabl…

Componentwise Linear Ideals From Sums

Hailong Dao, Sreehari Suresh-Babu

Let $I, J$ be componentwise linear ideals in a polynomial ring $S$ . We study necessary and sufficient conditions for $I + J$ to be componentwise linear. We provide a complete characte…

Betti numbers and linear covers of points

Hailong Dao, Ben Lund, Sreehari Suresh-Babu

We prove that for a finite set of points $X$ in the projective $n$ -space over any field, the Betti number $I^_{n, n + 1}^{2}$ of the coordinate ring of $X$ is non-zero if and only if $X$ …
