Rings with modules having a restricted injectivity domain
(SPRINGER INTERNATIONAL PUBLISHING AG, GEWERBESTRASSE 11, CHAM, CH-6330, SWITZERLAND, 2019)We introduce modules whose injectivity domains are contained in the class of modules with zero radical and call them working-class. This notion gives a generalization of poor modules that have minimal injectivity domain. ... -
RINGS WITH VARIATIONS OF FLAT COVERS
(HONAM MATHEMATICAL SOC, DEPT MATHEMATICS, COLL NATURAL SCIENCE, CHOSUN UNIV, 309, PILMUN-DAERO, DONG-GU, GWANGJU, 501-759, SOUTH KOREA, 2019)We introduce flat e-covers of modules and define e-perfect rings as a generalization of perfect rings. We prove that a ring is right perfect if and only if it is semilocal and right e-perfect which generalizes a result due ... -
A Semi-Analytic Method for Solving Singularly Perturbed Twin-Layer Problems with a Turning Point
(Vilnius Gediminas Technical University, 2023)This computational study investigates a class of singularly perturbed second-order boundary-value problems having dual (twin) boundary layers and simple turning points. It is well-known that the classical discretization ... -
Tailored Synthesis of Iron Oxide Nanocrystals for Formation of Cuboid Mesocrystals
(AMER CHEMICAL SOC1155 16TH ST, NW, WASHINGTON, DC 20036, 2021)In this work, we systematically studied the shape- and size-controlled monodisperse synthesis of iron oxide nanocrystals (IONCs) for their use as building blocks in the formation of mesocrystals. For this aim, on understanding ... -
WSA-Supplements and Proper Classes
(MDPIST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND, 2022)In this paper, we introduce the concept of wsa-supplements and investigate the objects of the class of short exact sequences determined by wsa-supplement submodules, where a submodule U of a module M is called a ...
