Closed binomial edge ideals

Journal für die reine und angewandte Mathematik (Crelles Journal), 2023
We prove a conjecture by Ene, Herzog, and Hibi (2011) that the Betti numbers of the binomial edge ideal J G {J_{G}} of a closed graph G coincide with the Betti numbers of its lex initial ideal M G {M_{G}} . We describe the Betti numbers of the ideal M G {

Binomial edge ideals of trees

Communications in Algebra
In this paper, we study the binomial edge ideals of trees. First, we analyze the associated prime ideals of these ideals. Next, we present a recursive method for computing the Hilbert series of binomial edge ideals of binary trees.

Depth of powers of binomial edge ideals of complete bipartite graphs

Communications in Algebra, 2023
Let be a complete bipartite graph on with and JG its binomial edge ideal in the polynomial ring over a field K. For any , it is proved that is equal to n + 1 if m = 1 and 4 if .

Partial Betti splittings with applications to binomial edge ideals

Collectanea Mathematica
We introduce the notion of a partial Betti splitting of a homogeneous ideal, generalizing the notion of a Betti splitting first given by Francisco, H\`a, and Van Tuyl.

Binomial Edge Ideals and Related Ideals

2018
In this chapter we consider classes of binomial ideals which are naturally attached to finite simple graphs. The first of these classes are the binomial edge ideals. These ideals may also be viewed as ideals generated by a subset of 2-minors of a (2 × n)-matrix of indeterminates. Their Grobner bases will be computed.
