Rings in which Every Simple Right R-Module is Flat [PDF]

open access: goldAl-Rafidain Journal of Computer Sciences and Mathematics, 2004
The objective of this paper is to initiate the study of rings in which each simple right R-module is flat, such rings will be called right SF-rings. Some important properties of right SF-rings are obtained.

On Simple Singular N-Flat Modules [PDF]

open access: goldAl-Rafidain Journal of Computer Sciences and Mathematics, 2013
Let I be a right ideal of a ring R , then R/I is right N-flat module if and only if for each , there exists  and a positive integer n such that  and  .In this paper, we first introduce and characterize rings whose every simple singular right R-module is ...

Simple and Low-Cost Shared-Aperture Antenna Module for 5G N78 and N257 Applications

open access: goldIEEE Open Journal of Antennas and Propagation
A simple and low-cost shared aperture antenna module for 5G N78 and N257 applications is proposed. This module integrates a microwave (MW) patch antenna and a millimeter wave (MMW) substrate-integrated waveguide (SIW) slot antenna.

Finite Dimensional Simple Modules over Some GIM Lie Algebras

open access: yesMathematics, 2022
GIM Lie algebras are the generalizations of Kac–Moody Lie algebras. However, the structures of GIM Lie algebras are more complex than the latter, so they have encountered many new difficulties to study their representation theory.

On simple modules with singular highest weights for so2l+1(K)

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
In this paper, we study formal characters of simple modules with singular highest weights over classical Lie algebras of type B over an algebraically closed field of characteristic p ≥ h, where h is the Coxeter number. Assume that the highest weights of

Strongly Maximal Submodules with A Study of Their Influence on Types of Modules

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2022
Let S be a commutative ring with identity, and A is an S-module. This paper introduced an important concept, namely strongly maximal submodule. Some properties and many results were proved as well as the behavior of that concept with its localization was
