On powers of the cover ideals of graphs

Dancheng Lu, Zexin Wang

For a simple graph $G$ , assume that $J (G)$ is the vertex cover ideal of $G$ and $J (G)^{(s)}$ is the $s$ -th symbolic power of $J (G)$ . We prove that $(J (C)^{(s)}) = (J (C)^{s})$ for all $…

Linear resolutions and quasi-linearity of monomial ideals

Dancheng Lu

We introduce the concept of quasi-linearity and prove it is necessary for a monomial ideal to have a linear resolution and identify all the quasi-linear quadratic monomial ideals.…
