Analytic Approximate Solutions of Parameterized Unperturbed And Singularly Perturbed Boundary Value Problems
(Elsevier Science Inc, 2011)A novel approach is presented in this paper for approximate solution of parameterized unperturbed and singularly perturbed two-point boundary value problems. The problem is first separated into a simultaneous system regarding ... -
An Alternative Perspective on Injectivity of Modules
(Academic Press Inc Elsevier Science, 2011)Given modules M and N, M is said to be N-subinjective if for every extension K of N and every homomorphism : N M there exists a homomorphism phi : K -> M such that phi vertical bar N = phi. For a module M, the subinjectivity ... -
An Analytic Shooting-Like Approach For The Solution of Nonlinear Boundary Value Problems
(Pergamon-Elsevier Science Ltd, 2011)In this paper a novel approach is presented for an analytic approximate solution of nonlinear differential equations with boundary conditions. By converting the nonlinear problem into an initial value form, a shooting-like ... -
An Optimal Variational Iteration Method
(Pergamon-Elsevier Science Ltd, 2011)The variational iteration method is studied in the present work. The classical variational iteration method is improved and extended by introducing a new concept of a convergence accelerating parameter. A rigorous approach ... -
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) ... -
Plain Ditopological Texture Spaces
(Elsevier Science Bv, 2011)Using the characterization of plain textures in terms of posets given by Mustafa Demirci (M. Demirci, Textures and C-spaces, Fuzzy Sets and Systems 158 (11) (2007) 1237-1245), the authors consider the important class of ... -
On The Second Equation Of Obata
(Mathematical Soc Rep China, 2011)In this paper we prove some results related to a certain vector field satisfying the second equation of Obata [8] on vector fields. -
Strong Lifting Splits
(Elsevier Science Bv, 2011)The concept of an enabling ideal is introduced so that an ideal I is strongly lifting if and only if it is lifting and enabling. These ideals are studied and their properties are described. It is shown that a left duo ring ... -
Some Issues On Hpm And Ham Methods: A Convergence Scheme
(Pergamon-Elsevier Science Ltd, 2011)The homotopy method for the solution of nonlinear equations is revisited in the present study. An analytic method is proposed for determining the valid region of convergence of control parameter of the homotopy series, as ... -
Definability And Textures
(Elsevier Science Inc, 2012)This paper aims to give a new perspective for definability in rough set theory. First, a counterpart of definability is introduced in textural approximation spaces. Then a complete field of sets for texture spaces is defined ... -
Rings Whose Cyclic Modules Are Direct Sums Of Extending Modules
(Cambridge Univ Press, 2012)Dedekind domains, Artinian serial rings and right uniserial rings share the following property: Every cyclic right module is a direct sum of uniform modules. We first prove the following improvement of the well-known ... -
Rings Close to Semiregular
(Korean Mathematical Soc, 2012)A ring R is called semiregular if R/J is regular and idempotents lift modulo J, where J denotes the Jacobson radical of R. We give some characterizations of rings R such that idempotents lift modulo J, and R/J satisfies ... -
Complex And Symplectic Structures On Panelled Web 4-Manifolds
(Elsevier Science Bv, 2012)We analyze the symplectic and complex structures on the panelled web 4-manifolds of S. Akbulut and M. Kalafat [1]. In particular, we give infinite families of examples of almost complex but not symplectic and not complex ... -
A Note on Ads* Modules
(Springer Basel Ag, 2012)We study the ADS* modules which are the dualizations of ADS modules studied by Alahmadi et al. ( J Algebra 352: 215-222, 2012). Mainly we prove that an amply supplemented module M is ADS* if and only if M-1 and M-2 are ... -
On Almost Contractions In Partially Ordered Metric Spaces Via Implicit Relations
(Springeropen, 2012)In this paper, we prove general fixed point theorems for self-maps of a partially ordered complete metric space which satisfy an implicit type relation. Our method relies on constructive arguments involving Picard type ... -
Di-Uniformities and Hutton Uniformities
(Elsevier Science Bv, 2012)The authors characterize di-uniformities on a texture (S, J) in the sense of Ozgag and Brown (Di-uniform texture spaces, Appl. Gen. Top. 4(1) (2003), 157-192) in terms of functions on the texturing J. This characterization ... -

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 ... -
Polygon Morphing and Its Application in Orebody Modeling
(Hindawi Publishing Corporation, 2012)Three different polygon morphing methods are examined. The first one is based on the utilization of the trimmed skeleton of the symmetric difference of the source and target polygons as an intermediate polygon. The second ... -
On Rad-D-12 Modules
(Ovidius Univ Press, 2013)Let M be a right R-module. We call M Rad-D-12, if for every submodule N of M, there exist a direct summand K of M and an epimorphism alpha : K -> M/N such that Ker alpha subset of Rad(K). We show that a direct summand of ...
