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.

Depth and Stanley Depth of the Edge Ideals of r-Fold Bristled Graphs of Some Graphs

open access: yesMathematics, 2023
In this paper, we find values of depth, Stanley depth, and projective dimension of the quotient rings of the edge ideals associated with r-fold bristled graphs of ladder graphs, circular ladder graphs, some king’s graphs, and circular king’s graphs.

Generalized multiplicities of edge ideals [PDF]

open access: yes, 2017
We explore connections between the generalized multiplicities of square-free monomial ideals and the combinatorial structure of the underlying hypergraphs using methods of commutative algebra and polyhedral geometry.

Ideal based hypergraph of a commutative ring

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
Let R be a commutative ring and k an integer strictly greater than 2. The k-maximal ideal hypergraph to R with vertex set the set of all k-maximal ideals in R and for distinct ideals I1, in the set is an edge of if and only if and the sum of any elements

Splittings of monomial ideals [PDF]

open access: yes, 2008
We provide some new conditions under which the graded Betti numbers of a monomial ideal can be computed in terms of the graded Betti numbers of smaller ideals, thus complementing Eliahou and Kervaire's splitting approach.

On the binomial edge ideals of block graphs

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2016
We find a class of block graphs whose binomial edge ideals have minimal regularity. As a consequence, we characterize the trees whose binomial edge ideals have minimal regularity.

open access: yesTransactions on Combinatorics, 2017
In this paper we introduce the concept of generalized trees and compute the Hilbert series of their binomial edge ideals‎.

Religious Dimensions in Transhumanist and Posthumanist Philosophies of Science

open access: yesConatus - Journal of Philosophy, 2021
The article discusses transhumanism and posthumanism as marginal trajectories of the modern philosophy of science, which, however, distinctly influence the mainstream narrative of science and societal relations.
