Binomial edge ideals of unicyclic graphs [PDF]

open access: yesInternational Journal of Algebra and Computation, 2021
Let [Formula: see text] be a connected graph on the vertex set [Formula: see text]. Then [Formula: see text]. In this paper, we prove that if [Formula: see text] is a unicyclic graph, then the depth of [Formula: see text] is bounded below by [Formula: see text]. Also, we characterize [Formula: see text] with [Formula: see text] and [Formula: see text].

Algebraic Algorithms for Even Circuits in Graphs

open access: yesMathematics, 2019
We present an algebraic algorithm to detect the existence of and to list all indecomposable even circuits in a given graph. We also discuss an application of our work to the study of directed cycles in digraphs.

Software-Defined Heterogeneous Edge Computing Network Resource Scheduling Based on Reinforcement Learning

open access: yesApplied Sciences, 2022
With the rapid development of wireless networks, wireless edge computing networks have been widely considered. The heterogeneous characteristics of the 6G edge computing network bring new challenges to network resource scheduling.

The v-number of edge ideals

open access: yesJournal of Combinatorial Theory, Series A, 2021
The aim of this work is to study the v-number of edge ideals of clutters and graphs. We relate the v-number with the regularity of edge ideals and study the combinatorial structure of the graphs whose edge ideals have their second symbolic power Cohen-Macaulay.

A Lower Bound For Depths of Powers of Edge Ideals [PDF]

open access: yes, 2015
Let $G$ be a graph and let $I$ be the edge ideal of $G$. Our main results in this article provide lower bounds for the depth of the first three powers of $I$ in terms of the diameter of $G$.

A NOTE ON MATCHINGS AND REGULARITY OF GRAPHS

open access: yesTạp chí Khoa học
Let 𝐺 be a simple graph. We introduce the notion of comb- match(𝐺), and prove that reg(𝐼(𝐺)) ≤ comb-match(𝐺)+1.

Generalized binomial edge ideals

open access: yesAdvances in Applied Mathematics, 2013
This paper studies a class of binomial ideals associated to graphs with finite vertex sets. They generalize the binomial edge ideals, and they arise in the study of conditional independence ideals. A Gr bner basis can be computed by studying paths in the graph.
