Generalized Semicommutative Rings And Their Extensions
(Korean Mathematical Soc, 2008)
For an endomorphism a of a ring R., the endomorphism a is called semicommutative if ab = 0 implies a Ha(b) = 0 for a is an element of R. A ring R is called alpha-semicommulative if there exists a semicommutative endomorphism ...
A Generalization of Projective Covers
(Academic Press Inc Elsevier Science, 2008)
Let M be a left module over a ring R and I an ideal of R. We call (P, f) a projective I-cover of M if f is an epimorphism from P to M, P is projective, Ker f subset of I P, and whenever P = Ker f + X, then there exists a ...
Finite-Dimensional Attractors For A General Class Of Nonautonomous Wave Equations
(Pergamon-Elsevier Science Ltd, 2000)
Our aim in this note is to construct attractors and exponential attractors for a general class of nonautonomous semilinear wave equations. Following the approach described in [1], we define a semigroup S(t) associated to ...
Fractional Calculus And Certain Starlike Functions With Negative Coefficients
(Pergamon-Elsevier Science Ltd, 1995)
A certain subclass T(n,p,lambda,alpha) of starlike functions in the unit disk is introduced. The object of the present paper is to derive several interesting properties of functions belonging to the class T(n,p,lambda,alpha). ...
Global Attractor For The One Dimensional Wave Equation With Displacement Dependent Damping
(Pergamon-Elsevier Science Ltd, 2012)
We study the long-time behavior of solutions of the one dimensional wave equation with nonlinear damping coefficient. We prove that if the damping coefficient function is strictly positive near the origin then this equation ...

On Existence And Nonexistence Of The Positive Solutions Of Non-Newtonian Filtration Equation
(Amer Inst Mathematical Sciences, 2011)
The subject this investigation is existence and nonexistence of positive solutions of the following nonhomogeneous equation rho(vertical bar x vertical bar) partial derivative u/partial derivative t - Sigma(N)(i=1) ...
On Hollow-Lifting Modules
(Mathematical Soc Rep China, 2007)
Let R be any ring and let M be any right R-module. M is called hollow-lifting if every submodule N of M such that M/N is hollow has a coessential submodule that is a direct summand of M. We prove that every amply supplemented ...
On Dual Baer Modules
(Cambridge Univ Press, 2010)
In this paper we introduce T-non-cosingular modules, dual Baer modules and K-modules. We prove that a module M is lifting and T-non-cosingular if and only if it is a dual Baer and K-module. Rings for which all modules are ...
