Projective class rings of a kind of category of Yetter-Drinfeld modules
AIMS Mathematics, 2023 In this paper, all simple Yetter-Drinfeld modules and indecomposable projective Yetter-Drinfeld modules over a family of non-pointed 8m-dimension Hopf algebras of tame type with rank two, are construted and classified.

Allowing for the Projective Dimension of Agency in Analysing Alternative Food Networks
Sociologia Ruralis, 2019 This article argues for including the projective dimension of agency in research into 15 alternative food networks. Starting from a review of the literature, I show that referring to the 16 notion of project is useful to answer the questions raised by ...

$\mathfrak{X}$-Gorenstein Projective Dimensions
Journal of Mathematical Study, 2022 In this paper, we mainly investigate the $\mathfrak{X}$-Gorenstein projective dimension of modules and the (left) $\mathfrak{X}$-Gorenstein global dimension of rings. Some properties of $\mathfrak{X}$-Gorenstein projective dimensions are obtained. Furthermore, we prove that the (left) $\mathfrak{X}$-Gorenstein global dimension of a ring $R$ is equal to

Codimension and projective dimension up to symmetry [PDF]
Mathematische Nachrichten, 2018 Symmetric ideals in increasingly larger polynomial rings that form an ascending chain are investigated. We focus on the asymptotic behavior of codimensions and projective dimensions of ideals in such a chain. If the ideals are graded it is known that the

Total Betti numbers of modules of finite projective dimension [PDF]
, 2017 The Buchsbaum-Eisenbud-Horrocks Conjecture predicts that if M is a non-zero module of finite length and finite projective dimension over a local ring R of dimension d, then the i-th Betti number of M is at least d choose i.

Projection pursuit in high dimensions [PDF]
Proceedings of the National Academy of Sciences, 2018 SignificanceA key challenge in analyzing high-dimensional data is to extract meaningful low-dimensional structures, which typically represent signals of interest. Standard and widely used methods include principal components analysis (PCA), independent component analysis (ICA), and projection pursuit.

Characterization and Lower Bounds for Branching Program Size using Projective Dimension [PDF]
, 2016 We study projective dimension, a graph parameter (denoted by pd$(G)$ for a graph $G$), introduced by (Pudl\'ak, R\"odl 1992), who showed that proving lower bounds for pd$(G_f)$ for bipartite graphs $G_f$ associated with a Boolean function $f$ imply size ...

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

Base manifolds for fibrations of projective irreducible symplectic manifolds [PDF]
, 2007 Given a projective irreducible symplectic manifold $M$ of dimension $2n$, a projective manifold $X$ and a surjective holomorphic map $f:M \to X$ with connected fibers of positive dimension, we prove that $X$ is biholomorphic to the projective space of ...
