Absolutely spure modules and neatflat modules
(Taylor & Francis, 201502)Let R be a ring with an identity element. We prove that R is right Kasch if and only if injective hull of every simple right Rmodules is neatflat if and only if every absolutely pure right Rmodule is neatflat. A ...

A biomathematical model for Phoma tracheiphila citrus resistance screening
(Taylor & Francis, 201210)The causal agent of Mal Secco, Phoma tracheiphila, is responsible for many important losses in the Citrus crop worldwide. The resistance enhancement of Citrus susceptible to the pathogen infection depends on the availability ... 
Boosting the decay of solutions of the linearised Kortewegde Vries–Burgers equation to a predetermined rate from the boundary
(Taylor & Francis, 2019)The aim of this article is to extend recent results on the boundary feedback controllability of the Kortewegde Vries equation to the Kortewegde Vries–Burgers equation which is posed on a bounded domain. In the first part ... 
Cofinitely weak supplemented modules
(Taylor & Francis, 200311)We prove that a module M is cofinitely weak supplemented or briefly cws (i.e., every submodule N of M with M/N finitely generated, has a weak supplement) if and only if every maximal submodule has a weak supplement. If M ... 
The convergence of a new symmetric iterative splitting method for nonautonomous systems
(Taylor & Francis, 201209)The iterative splitting methods have been extensively applied to solve complicated systems of differential equations. In this process, we split the complex problem into several subproblems, each of which can be solved ... 
A fully discrete εuniform method for singular perturbation problems on equidistant meshes
(Taylor & Francis, 201201)We propose a fully discrete εuniform finitedifference method on an equidistant mesh for a singularly perturbed twopoint boundaryvalue problem (BVP). We start with a fitted operator method reflecting the singular ... 
Neatflat modules
(Taylor & Francis, 201601)Let R be a ring. A right Rmodule M is said to be neatflat if the kernel of any epimorphism Y → M is neat in Y, i.e., the induced map Hom(S, Y) → Hom(S, M) is surjective for any simple right Rmodule S. Neatflat right ... 
Poor and pipoor Abelian groups
(Taylor & Francis, 201701)In this paper, poor abelian groups are characterized. It is proved that an abelian group is poor if and only if its torsion part contains a direct summand isomorphic to (Formula presented.) , where P is the set of prime ... 
The proper class generated by weak supplements
(Taylor & Francis, 201401)We show that, for hereditary rings, the smallest proper classes containing respectively the classes of short exact sequences determined by small submodules, submodules that have supplements and weak supplement submodules ...
