∑-extending modules

open access: yesJournal of Pure and Applied Algebra, 1995
AbstractAn R-module M is called ∑-extending if every coproduct of copies of M is extending, i.e. closed submodules are direct summands.Oshiro (1984) has shown that the ring R is ∑-extending as a left module if and only if the class of projective R->modules is closed under essential extensions.

Directed network modules [PDF]

open access: yes, 2007
A search technique locating network modules, i.e., internally densely connected groups of nodes in directed networks is introduced by extending the Clique Percolation Method originally proposed for undirected networks.

Vertex Algebras $\mathcal{W}(p)^{A_m}$ and $\mathcal{W}(p)^{D_m}$ and Constant Term Identities [PDF]

open access: yes, 2015
We consider $AD$-type orbifolds of the triplet vertex algebras $\mathcal{W}(p)$ extending the well-known $c=1$ orbifolds of lattice vertex algebras. We study the structure of Zhu's algebras $A(\mathcal{W}(p)^{A_m})$ and $A(\mathcal{W}(p)^{D_m})$, where ...

On Strongly Extending Modules

open access: yesKyungpook mathematical journal, 2014
The study of extending modules has emerged as a major topic in module theory and several related concepts have been studied. The class of strongly extending modules, a subclass of the class of extending modules, is defined and studied in this paper. An \(R\)-module \(M\) is said to be strongly extending if, for any submodule \(N\) of \(M\), a fully ...

On Min - Cs Modules and Some Related Concepts

open access: yesمجلة بغداد للعلوم, 2014
Our aim in this paper is to study the relationships between min-cs modules and some other known generalizations of cs-modules such as ECS-modules, P-extending modules and n-extending modules.

e*-Extending Modules

open access: yesIraqi Journal of Science, 2023
     This paper aims to introduce the concepts of  -closed, -coclosed, and -extending modules as generalizations of the closed, coclossed, and extending modules,  respectively. We will prove some properties as when the image of the e*-closed submodule is also e*-closed and when the submodule of the e*-extending module is e*-extending. Under isomorphism,

Programmable photovoltaic submodules for hotspot mitigation

open access: yesInternational Journal of Sustainable Engineering, 2023
This paper introduces a novel approach to conventional Photovoltaic (PV) modules that involves regulating the internal connections of the PV strings (or submodules) using a set of switches to isolate shaded submodules while leaving unshaded submodules ...

Poset structures in Boij-S\"oderberg theory [PDF]

open access: yes, 2011
Boij-S\"oderberg theory is the study of two cones: the cone of cohomology tables of coherent sheaves over projective space and the cone of standard graded minimal free resolutions over a polynomial ring.
