The v-number of binomial edge ideals

SB Ambhore, K Saha, I Sengupta - Acta Mathematica Vietnamica, 2024 - Springer
The invariant v-number was introduced very recently in the study of Reed-Muller-type codes.
Jaramillo and Villarreal (J. Combin. Theory Ser. A 177: 105310,) initiated the study of the v …

[HTML][HTML] Connected domination in graphs and v-numbers of binomial edge ideals

D Jaramillo-Velez, L Seccia - Collectanea Mathematica, 2023 - Springer
The v-number of a graded ideal is an algebraic invariant introduced by Cooper et al., and
originally motivated by problems in algebraic coding theory. In this paper we study the case …

[HTML][HTML] 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 …

Cohen-Macaulay Binomial edge ideals in terms of blocks with whiskers

K Saha, I Sengupta - arXiv preprint arXiv:2203.04652, 2022 - arxiv.org
For a graph $ G $, Bolognini et al. have shown $ J_ {G} $ is strongly unmixed $\Rightarrow
$$ J_ {G} $ is Cohen-Macaulay $\Rightarrow $$ G $ is accessible, where $ J_ {G} $ denotes …

Rees algebra and special fiber ring of binomial edge ideals of closed graphs

A Kumar - Illinois Journal of Mathematics, 2022 - projecteuclid.org
In this paper, I compute the regularity of the Rees algebra of binomial edge ideals of closed
graphs. I obtain a lower bound for the regularity of the Rees algebra of binomial edge ideals …

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 …
