Algebraic invariants of the edge ideals of whisker graphs of cubic circulant graphs [PDF]

open access: yesHeliyon
Let Q be a polynomial ring over a field F and I be an edge ideal associated with the whisker graph of a cubic circulant graph. We discuss the regularity, depth, Stanley depth, and projective dimension of Q/I.

On the Stanley depth of weakly polymatroidal ideals [PDF]

open access: yesArchiv Der Mathematik, 2013
Let \(S=k[x_1,\dots,x_n ]\) with \(k\) a field. In [Invent. Math. 68, 175--193 (1982; Zbl 0516.10009)], \textit{R. P. Stanley} conjectured that for any finitely generated \(\mathbb{Z}^n\)-graded \(S\)-module \(M\) one always has that \(\mathrm{sdepth} (M)\geq \mathrm{depth} (M)\) i.e. that the Stanley depth is always greater than or equal to the depth.

An algorithm to compute the Stanley depth of monomial ideals

open access: yesLe Matematiche, 2008
In this article we describe an algorithm to compute the Stanley depth of I=J where I and J are monomial ideals. We describe also an implementation in CoCoA.

A non-partitionable Cohen–Macaulay simplicial complex [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2020
A long-standing conjecture of Stanley states that every Cohen–Macaulay simplicial complex is partition- able. We disprove the conjecture by constructing an explicit counterexample.

TRANSFER OF HEAVY METALS IN SOIL IN-PLUM CULTIVATION: A FIELD STUDY IN ADAMACHI IASI, ROMANIA [PDF]

open access: yesJournal of Applied Life Sciences and Environment, 2023
Currently, global environmental concerns about heavy metal pollution are driven by rapid urbanization and industrial development. Therefore, a field study was conducted to assess the concentration of heavy metals (Pb, Co, Zn, Ni and Cu) in orchard soils ...

Stanley Depth of the Edge Ideal of Extended Gear Networks and Application in Circuit Analysis

open access: yesJournal of Mathematics, 2022
Graph theory is widely used in power network analysis, complex network, and engineering calculation. Stanley depth is a geometric invariant of the module which is closely related to an algebraic invariant called depth of the module.

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.
