Projective dimension and regularity of path ideals of cycles [PDF]

open access: yesJournal of Algebra and its Applications, 2016
In this paper, we study the generalized path ideals, which is a new class of path ideals of cycle graphs. These ideals naturally generalize the standard path ideals of cycles, as studied by Alilooee and Faridi [On the resolution of path ideals of cycles,

Resolutions of monomial ideals of projective dimension 1 [PDF]

open access: yes, 2017
We show that a monomial ideal I in a polynomial ring S has projective dimension ≤ 1 if and only if the minimal free resolution of S∕I is supported on a graph that is a tree. This is done by constructing specific graphs which support the resolution of the

Hypergraphs with high projective dimension and 1-dimensional hypergraphs [PDF]

open access: yesInternational journal of algebra and computation, 2016
We prove a sufficient and a necessary condition for a square-free monomial ideal $J$ associated to a (dual) hypergraph to have projective dimension equal to the minimal number of generators of $J$ minus 2.

Bounds on the regularity and projective dimension of ideals associated to graphs [PDF]

open access: yesJournal of Algebraic Combinatorics, 2012
In this paper, we give new upper bounds on the regularity of edge ideals whose resolutions are k-step linear; surprisingly, the bounds are logarithmic in the number of variables.

Projective dimension and regularity of the path ideal of the line graph [PDF]

open access: yes, 2016
By generalizing the notion of the path ideal of a graph, we study some algebraic properties of some path ideals associated to a line graph. We show that the quotient ring of these ideals are always sequentially Cohen–Macaulay and also provide some exact ...

Dislocated function projective partial synchronization between dynamical systems

open access: yesAlexandria Engineering Journal, 2023
By generalizing the classical Lorenz chaotic system, we construct the n-dimension and m-dimension dynamical systems as the drive system and response one respectively.

Ding-同调模的稳定性(Stability of Ding homological modules)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2015
A homological characterization of the Ding projective dimensions of modules over arbitrary associative rings is give. Also, we prove that an iteration of the procedure used to define the Ding projective modules yields exactly the Ding projective modules.

Frobenius Betti numbers and modules of finite projective dimension [PDF]

open access: yes, 2014
Let $(R,\mathfrak{m},K)$ be a local ring, and let $M$ be an $R$-module of finite length. We study asymptotic invariants, $\beta^F_i(M,R),$ defined by twisting with Frobenius the free resolution of $M$.

Le corps comme cadre et surface de projection chez Gina Pane et Pier Paolo Pasolini

open access: yesImages Re-Vues, 2022
This article focuses on the conception of frame elaborated by Pier Paolo Pasolini and Gina Pane in their respective works. It is first of all a matter of observing the role of the projection device in the genesis of their relationship to framing. Between
