On the Arithmetical Rank of the Edge Ideals of Some Graphs
- Fatemeh Mohammadi and
- Dariush Kiani
Algebra Colloquium31 Oct 2012
Preview Abstract
In this paper, we compute the projective dimension of the edge ideals of graphs consisting of some cycles and lines which are joint in a common vertex. Moreover, we show that for such graphs, the arithmetical rank equals the projective dimension. As an application, we can compute the arithmetical rank for some homogenous monomial ideals.

Edge Ideals with Regularity No More than Three
- Aming Liu and
- Tongsuo Wu
Algebra Colloquium05 Nov 2020
Preview Abstract
We prove that if G is a gap-free and chair-free simple graph, then the regularity of the edge ideal of G is no more than 3. If G is a gap-free and P₄-free graph, then it is a chair-free graph; furthermore, the complement of G is chordal, and thus the regularity of G is 2.
