Explicit bounds of unknown function of some new weakly singular retarded integral inequalities for discontinuous functions and their applications [PDF]

Journal of Inequalities and Applications, 2017
The purpose of the present paper is to establish some new retarded weakly singular integral inequalities of Gronwall-Bellman type for discontinuous functions, which generalize some known weakly singular and impulsive integral inequalities.

On the convergence rate of collocation methods for Volterra integral equations with weakly singular oscillatory trigonometric kernels

Results in Applied Mathematics, 2023
This paper presents efficient collocation methods for linear Volterra integral equations with weakly singular highly oscillatory kernels. The numerical steepest descent method and generalized Gauss–Laguerre rule are utilized to calculate the weakly ...

Characterizations of Weakly Approximately Primary Submodules in Some Types of Modules

Tikrit Journal of Pure Science, 2021
Our aim in this note is to introduce several characterizations of weakly approximately primary submodules in class of multiplication modules. Furthermore, we characterized weakly approximately primary submodules by theirs resudule in the class of ...

Weakly-exceptional quotient singularities [PDF]

Open Mathematics, 2012
Abstract A singularity is said to be weakly-exceptional if it has a unique purely log terminal blow-up. In dimension 2, V. Shokurov proved that weakly-exceptional quotient singularities are exactly those of types D n, E 6, E 7, E 8. This paper

Some New Nonlinear Weakly Singular Inequalities and Applications to Volterra-Type Difference Equation

Abstract and Applied Analysis, 2013
Some new nonlinear weakly singular difference inequalities are discussed, which generalize some known weakly singular inequalities and can be used in the analysis of nonlinear Volterra-type difference equations with weakly singular kernel. An application

Idempotent Reflexive rings whose every simle singular right module are yj-injective [PDF]

المجلة العراقية للعلوم الاحصائية, 2011
In this paper we study rightidempotent reflexive ring whose simple singular right R-module isYJ-injective, we prove that this type of ring is right weakly regular ring, we show that if R is N duo or NCI ring and R is right idempotent reflexive ring ...
