Journal 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.

Modules which are self-p-injective relative to projection invariant submodules
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 In this article, we focus on modules M such that every homomorphism from a projection invariant submodule of M to M can be lifted to M. Although such modules share some of the properties of PI -extending (i.e., every projection invariant submodule is ...

Symmetry, Integrability and Geometry: Methods and Applications, 2013 We prove a family of 3-term relations in the Grothendieck ring of the category of finite-dimensional modules over the affine quantum algebra of type G2 extending the celebrated T-system relations of type G2.

On Closed Dual Rickart Modules
Journal of Kufa for Mathematics and Computer, 2017 The notion of dual Rickart modules has been studied lately. In this article, we continue investigate and study several properties of closed dual Rickart modules which explain by Ghawi Th.Y.

On $\mu $-singular and $\mu $-extending modules
, 2012 summary:Let $M$ be a module and $\mu $ be a class of modules in $\operatorname{Mod}-R$ which is closed under isomorphisms and submodules. As a generalization of essential submodules Özcan in [8] defines a $\mu $-essential submodule provided it has a non ...

Renovation of radio-electronic devices by reengineerin
Технологія та конструювання в електронній апаратурі, 2023 Domestic radio-electronics, which is still incorporated in many electronic devices, has practically exhausted its technical resource. The longer modernization is postponed and the radio-electronic equipment based on outdated elements remains in use, the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

T-Stable-extending Modules and Strongly T- stable Extending Modules
Iraqi Journal of Science, 2020 In this paper we introduce the notions of t-stable extending and strongly t-stable extending modules. We investigate properties and characterizations of each of these concepts. It is shown that a direct sum of t-stable extending modules is t-stable extending while with certain conditions a direct sum of strongly t-stable extending is strongly t ...

International Journal of Mathematics and Mathematical Sciences, 2002 We develop some basic functorial techniques for the study of the categories of comodules over corings. In particular, we prove that the induction functor stemming from every morphism of corings has a left adjoint, called ad-induction functor.
