Admissibility of Localizations of Crossed Modules

open access: yesApplied Categorical Structures, 2023
AbstractThe correspondence between the concept of conditional flatness and admissibility in the sense of Galois appears in the context of localization functors in any semi-abelian category admitting a fiberwise localization. It is then natural to wonder what happens in the category of crossed modules where fiberwise localization is not always available.

On the simplicity crossed polymodules

open access: yesJournal of New Results in Science, 2023
The conception of crossed modules was first expressed by Whitehead when he was working on combinatorial theory. This concept has many uses in various fields, such as category theory, algebra, and k-theory. Moreover, one of the equations that plays a very

Crossed Modules of Monoids II: Relative Crossed Modules [PDF]

open access: yesApplied Categorical Structures, 2020
AbstractThis is the second part of a series of three strongly related papers in which three equivalent structures are studied:Internal categories in categories of monoids; defined in terms of pullbacks relative to a chosen class of spans.Crossed modules of monoids relative to this class of spans.Simplicial monoids of so-called Moore length 1 relative ...

A Note on 4-Dimensional 2-Crossed Modules

open access: yesJournal of New Theory, 2023
The study presents the direct product of two objects in the category of 4-dimensional 2-crossed modules. The structures of the domain, kernel, image, and codomain can be related using isomorphism theorems by defining the kernel and image of a morphism ...

The universal property of commutative algebras' internal crossed modules

open access: yesJournal of New Results in Science, 2023
In this work, we identify subobjects and ideals in the category of internal crossed modules, which provide a deeper understanding of the structure of these objects.

The non-abelian tensor product of normal crossed submodules of groups [PDF]

open access: yesCategories and General Algebraic Structures with Applications, 2020
In this article, the notions of non-abelian tensor and exterior products of two normal crossed submodules of a given crossed module of groups are introduced and some of their basic properties are established.

Universal enveloping crossed module of a Lie crossed module [PDF]

open access: yesHomology, Homotopy and Applications, 2014
Crossed modules of Lie algebras are interesting from several points of view: Crossed modules can be interpreted as easy (``strict'') Lie 2-algebras, they represent 3-cohomology classes and are linked to extension theory. Similar statements apply to crossed modules of associative algebras.

On Lie bialgebroid crossed modules [PDF]

open access: yesInternational Journal of Mathematics, 2021
We study Lie bialgebroid crossed modules which are pairs of Lie algebroid crossed modules in duality that canonically give rise to Lie bialgebroids. A one-one correspondence between such Lie bialgebroid crossed modules and co-quadratic Manin triples [Formula: see text] is established, where [Formula: see text] is a co-quadratic Lie algebroid and ...

Crossed Modules, Double Group-Groupoids and Crossed Squares [PDF]

open access: yes, 2020
The purpose of this paper is to obtain the notion of crossed module over group-groupoids considering split extensions and prove a categorical equivalence between these types of crossed modules and double group-groupoids.

On Modules and Crossed Modules

open access: yesJournal of Algebra, 1996
This is an elegant paper which, as claimed by the authors, is ``without any result''. It is a `meditation on the concept of module'. By examining a possible unifying concept of crossed module and modulated model in a very general context of algebraic theories, the authors then examine how these concepts clarify the various examples of module, crossed ...
