Cohen–Macaulay binomial edge ideals and accessible graphs

D Bolognini, A Macchia, F Strazzanti - Journal of Algebraic Combinatorics, 2022 - Springer
The cut sets of a graph are special sets of vertices whose removal disconnects the graph.
They are fundamental in the study of binomial edge ideals, since they encode their minimal …

A proof for a conjecture on the regularity of binomial edge ideals

MR Malayeri, SS Madani, D Kiani - Journal of Combinatorial Theory, Series …, 2021 - Elsevier
In this paper we introduce the concept of clique disjoint edge sets in graphs. Then, for a
graph G, we define the invariant η (G) as the maximum size of a clique disjoint edge set in G …

Binomial edge ideals of unicyclic graphs

R Sarkar - International Journal of Algebra and Computation, 2021 - World Scientific
Let G be a connected graph on the vertex set [n]. Then depth (S/JG)≤ n+ 1. In this paper, we
prove that if G is a unicyclic graph, then the depth of S/JG is bounded below by n. Also, we …
