The v-numbers and linear presentations of ideals of covers of graphs

Humberto Muñoz-George, Enrique Reyes, Rafael H. Villarreal

Let $G$ be a graph and let $J=I_c(G)$ be its ideal of covers. The aims of this work are to study the {\rm v}-number $\mathrm{v}(J)$ of $J$ and to study when $J$ is linearly presented…
