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.

On bounds of homological dimensions in Nakayama algebras [PDF]

open access: yes, 2017
Let $A$ be a Nakayama algebra with $n$ simple modules and a simple module $S$ of even projective dimension $m$. Choose $m$ minimal such that a simple $A$-module with projective dimension $2m$ exists, then we show that the global dimension of $A$ is ...

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.

Bounding Projective Dimension [PDF]

open access: yes, 2012
This paper is a survey of progress on Stillman’s Question: Let J be a homogeneous ideal in a standard graded polynomial ring over a field. Is there a bound on the projective dimension of J depending only on the number of elements in a minimal system of homogenoeus generators of J and their degrees (in particular, independent of the number of variables)?

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

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.

Arithmetic fake projective spaces and arithmetic fake grassmannians [PDF]

open access: yes, 2008
We show that if n>5, PU(n-1,1) does not contain a cocompact arithmetic subgroup with the same Euler-Poincare characteristic (in the sense of C.T.C. Wall) as the complex projective space of dimension n-1, and show that if n=5, there are at least four such

Homomorphisms of planar signed graphs to signed projective cubes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
We conjecture that every signed graph of unbalanced girth 2g, whose underlying graph is bipartite and planar, admits a homomorphism to the signed projective cube of dimension 2g1.

Projective toric designs, quantum state designs, and mutually unbiased bases [PDF]

open access: yesQuantum
Toric $t$-designs, or equivalently $t$-designs on the diagonal subgroup of the unitary group, are sets of points on the torus over which sums reproduce integrals of degree $t$ monomials over the full torus.
