A beginner's guide to edge and cover ideals

A Van Tuyl - Monomial ideals, computations and applications, 2013 - Springer
Monomial ideals, although intrinsically interesting, play an important role in studying the
connections between commutative algebra and combinatorics. Broadly speaking, problems …

Regularity 3 in edge ideals associated to bipartite graphs

O Fernández-Ramos, P Gimenez - Journal of Algebraic Combinatorics, 2014 - Springer
We focus in this paper on edge ideals associated to bipartite graphs and give a
combinatorial characterization of those having regularity 3. When the regularity is strictly …

Regularity of edge ideals of C4-free graphs via the topology of the lcm-lattice

E Nevo - Journal of Combinatorial Theory, Series A, 2011 - Elsevier
We study the topology of the lcm-lattice of edge ideals and derive upper bounds on the
Castelnuovo–Mumford regularity of the ideals. In this context it is natural to restrict to the …

Nonvanishing of Betti numbers of edge ideals and complete bipartite subgraphs

K Kimura - Communications in Algebra, 2016 - Taylor & Francis
Given a finite simple graph, one can associate the edge ideal. In this article, we prove that a
graded Betti number of the edge ideal does not vanish if the original graph contains a set of …

[图书][B] Monomial ideals, computations and applications

Monomial ideals and algebras are among the simplest structures in commutative algebra
and the main objects in combinatorial commutative algebra. One can highlight several …

[HTML][HTML] Polar syzygies in characteristic zero: the monomial case

I Bermejo, P Gimenez, A Simis - Journal of pure and applied algebra, 2009 - Elsevier
Given a set of forms f={f1,…, fm}⊂ R= k [x1,…, xn], where k is a field of characteristic zero,
we focus on the first syzygy module Z of the transposed Jacobian module D (f), whose …

Regularity and Free Resolution of Ideals which are Minimal to d-linearity

M Morales, AAY Pour, R Zaare-Nahandi - Mathematica Scandinavica, 2016 - JSTOR
For given positive integers n≥ d, a d-uniform clutter on a vertex set n= 1,..., n) is a collection
of distinct d-subsets of n. Let C be a d-uniform clutter on n. We may naturally associate an …

Regularity via topology of the lcm-lattice for -free graphs

E Nevo - arXiv preprint arXiv:0909.2801, 2009 - arxiv.org
We study the topology of the lcm-lattice of edge ideals and derive upper bounds on the
Castelnuovo-Mumford regularity of the ideals. In this context it is natural to restrict to the …
