Componentwise Linearity of Powers of Cover Ideals

S. Selvaraja, Joseph W. Skelton

Let $G$ be a finite simple graph and $J (G)$ denote its vertex cover ideal in a polynomial ring over a field. % $K$ . The $k$ -th symbolic power of $J (G)$ is denoted by $J(G)…

Symbolic Powers of Cover Ideals of Graphs and Koszul Property

Yan Gu, Huy Tài Hà, Joseph W. Skelton

We show that attaching a whisker (or a pendant) at the vertices of a cycle cover of a graph results in a new graph with the following property: all symbolic powers of its cover ide…

Symbolic powers of edge ideals of graphs

Yan Gu, Huy Tai Ha, Jonathan L. O'Rourke +1

Let $G$ be a graph and let $I = I (G)$ be its edge ideal. When $G$ is unicyclic, we give a decomposition of symbolic powers of $I$ in terms of its ordinary powers. This allows us to…
