[HTML][HTML] Letterplace and co-letterplace ideals of posets

G Fløystad, BM Greve, J Herzog - Journal of Pure and Applied Algebra, 2017 - Elsevier
To a natural number n, a finite partially ordered set P and a poset ideal J in the poset Hom

The aim of this book is to provide a theoretical framework to study monomial rings and ideals
associated to graphs, using techniques from graph theory, polyhedral geometry …

Edge ideals of clique clutters of comparability graphs and the normality of monomial ideals

LA Dupont, RH Villarreal - Mathematica scandinavica, 2010 - JSTOR
The normality of a monomial ideal is expressed in terms of lattice points of blocking
polyhedra and the integer decomposition property. For edge ideals of clutters this property …

A generalization of Eagon–Reiner's theorem and a characterization of bi-CMt bipartite and chordal graphs

H Haghighi, SAS Fakhari, S Yassemi… - Communications in …, 2018 - Taylor & Francis
We give a generalization of Eagon-Reiner's theorem relating Betti numbers of the Stanley-
Reisner ideal of a simplicial complex and the CM t property of its Alexander dual. Then we …

Cellular resolutions of Cohen-Macaulay monomial ideals

G Fløystad - Journal of Commutative Algebra, 2009 - JSTOR
We investigate monomial labelings on cell complexes, giving a minimal cellular resolution of
the ideal generated by these monomials, and such that the associated quotient ring is …

Bi-Cohen-Macaulay graphs

J Herzog, A Rahimi - arxiv preprint arxiv:1508.07119, 2015 - arxiv.org
In this paper we consider bi-Cohen-Macaulay graphs, and give a complete classification of
such graphs in the case they are bipartite or chordal. General bi-Cohen-Macaulay graphs …
