Projective Dimension of Some Graphs

Creative Mathematics and Informatics, 2022
In this paper exact values for the projective dimension of edge ideals associated to some star related graphs and product graphs $G\ \square\ P_2$, when $G=\ C_n,\ K_n$ and upper bounds for the projective dimension when $G=\ P_n,\ W_n$, are obtained. We have proved that $pd(C_{n+1}\ \square\ P_2)= 2\big(n-\left\lfloor \frac{n}{4}\right\rfloor\big)

Erasmus+ Project „DiMenSion“

2019
Against the backdrop of a generally increasing orientation towards exceptional customer experiences across businesses (cf. Pine/Gilmore 1999), marketing events have become an integral part of effective marketing communications. According to recent sector research, companies’ budgets for Live Communication have constantly risen in past years, and ...

Finite Phantom Projective Dimension

American Journal of Mathematics, 1994
A finitely generated \(R\)-module \(M\) is said to have a ``phantom resolution'' if there exists a complex of finitely generated projective \(R\)-modules \(P_ \bullet\) such that \(H_ 0 (P_ \bullet) = M\) and the module of cycles \(Z_ i (F^ e (P_ \bullet))\) is contained in the tight closure of the module of boundaries \(B_ i (F^ e (P_ \bullet))\) for ...

Packing dimensions of projections and dimension profiles

Mathematical Proceedings of the Cambridge Philosophical Society, 1997
Let \(E\subset\mathbb{R}^n\) be an analytic set and \(\mu\in{\mathfrak M}^+_c(E)\) a finite Borel measure on \(E\) with compact support. For a real number \(s\) with \(0\leq s\leq n\) put \[ F^\mu_s(x,r)= \int_{\mathbb{R}^n}\min\{1,r^s|y-x|^{-s}\}d\mu(y).

Filtering modules of finite projective dimension

Forum Mathematicum, 2003
For a right Artinian ring \(\Lambda\), denote by \(\text{Mod\,}\Lambda\) the category of all left \(\Lambda\)-modules. In the paper under review, the authors describe certain contravariantly finite resolving subcategories of \(\text{Mod\,}\Lambda\) which leads to some nice consequences as follows.
