Smoothness in Binomial Edge Ideals [PDF]

open access: yesMathematics, 2016
In this paper we study some geometric properties of the algebraic set associated to the binomial edge ideal of a graph. We study the singularity and smoothness of the algebraic set associated to the binomial edge ideal of a graph. Some of these algebraic

Licci binomial edge ideals [PDF]

open access: yesJournal of Combinatorial Theory - Series A, 2020
We give a complete characterization of graphs whose binomial edge ideal is licci. An important tool is a new general upper bound for the regularity of binomial edge ideals.

Gorenstein binomial edge ideals [PDF]

open access: yesMathematische Nachrichten, 2021
AbstractWe classify connected graphs G whose binomial edge ideal is Gorenstein. In our proofs we use Frobenius type techniques and F‐pure thresholds.

The regularity of binomial edge ideals of graphs [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2020
In this paper, we study the Castelnuovo-Mumford regularity and the graded Betti numbers of the binomial edge ideals of some classes of graphs. Our special attention is devoted to a conjecture which asserts that the number of maximal cliques of a graph ...

Koszul binomial edge ideals

open access: yesForum of Mathematics, Sigma
The study of Koszul binomial edge ideals was initiated by V. Ene, J. Herzog, and T. Hibi in 2014, who found necessary conditions for Koszulness. The binomial edge ideal $J_G$ associated to a finite simple graph G is always generated by quadrics ...

Binomial Edge Ideals of Graphs [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
We characterize all graphs whose binomial edge ideals have a linear resolution. Indeed, we show that complete graphs are the only graphs with this property. We also compute some graded components of the first Betti number of the binomial edge ideal of a graph with respect to the graphical terms.
