Maximal representation dimension of finite p-groups [PDF]

open access: yesJournal of Group Theory, 2010
The representation dimension of a finite group G is the smallest positive integer m for which there exists an embedding of G in GL_m(C). In this paper we find the largest value of representation dimensions, as Granges over all groups of order p^n, for a ...

On the representation dimension of artin algebras

open access: yes, 2011
The representation dimension of an artin algebra as introduced by M.Auslander in his Queen Mary Notes is the minimal possible global dimension of the endomorphism ring of a generator-cogenerator.

Dimensionality Reduction Method Combining Representation Learning and Embedded Subspace Learning [PDF]

open access: yesJisuanji gongcheng, 2021
When reducing the dimension of sample data, the subspace learning model cannot reveal the data structure or process new samples apart from the training samples.This paper proposes a dimension reduction method that fuses representation learning and ...

Alle origini del simbolismo medievale [PDF]

open access: yesPapireto, 2023
In the Middle Ages, the dimension of the imaginary often confu-sed the perception of reality with a process of abstraction. In this way, the representation of a cathedral could at the same time be the very idea of the cathedral. The imaginary was part of

A novel approach for dimension reduction using word embedding: An enhanced text classification approach

open access: yesInternational Journal of Information Management Data Insights, 2022
One of the challenging tasks in text classification is to reduce the dimensional feature space. This paper discusses an enhanced text classification method using Bag-of-Words representation model with term frequency-inverse document frequency (tf-idf ...

A note on defect Mellin amplitudes

open access: yesJournal of High Energy Physics, 2023
We generalize the Mellin representation for a generic co-dimension flat defect CFT. We study the analytic structure of the Mellin amplitudes. We also compute Witten diagrams for a generic co-dimension flat defect CFT.

Representation Dimension of Cluster-Concealed Algebras [PDF]

open access: yesAlgebras and Representation Theory, 2012
We are going to show that the representation dimension of a cluster-concealed algebra B is 3. We compute its representation dimension by showing an explicit Auslander generator for the cluster-tilted algebra.

On Partition Dimension of Generalized Convex Polytopes

open access: yesJournal of Mathematics, 2023
Let G be a graph having no loop or multiple edges, k−order vertex partition for G is represented by γ=γ1,γ2,…,γk. The vector rϕγ=dϕ,γ1,dϕ,γ2,dϕ,γ3⋯,dϕ,γk is the representation of vertex ϕ with respect to γ.

Big Finitistic Dimensions for Categories of Quiver Representations [PDF]

open access: yesMathematics Interdisciplinary Research, 2021
Assume that A is a Grothendieck category and R is the category of all A-representations of a given quiver Q. If Q is left rooted and A has a projective generator, we prove that the big finitistic flat (resp. projective) dimension FFD(A) (resp. FPD(A)) of
