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 ... -
Defining The K(Th) Powers Of The Dirac-Delta Distribution For Negative Integers
(Pergamon-Elsevier Science Ltd, 2001)In [1], Koh and Kuan defined the powers of the Dirac-delta distribution for positive integers. Here we extend their definition for negative integers. Also, we give meaning to the distribution delta (-kappa)(+). (C) 2001 ... -
Di-Extremities And Totally Bounded Di-Uniformities
(Univ Nis, Fac Sci Math, 2018)In our previous studies, we have defined a counterpart, called a di-extremity, to the classical notion proximity in the complement-free setting of a texture. In this article, we will investigate relationship between totally ... -
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 ... -
Dicompleteness And Real Dicompactness Of Ditopological Texture Spaces
(Elsevier Science Bv, 2011)The authors consider interrelations between the completeness of certain initial diuniformities and the real dicompactness of completely biregular bi-T-2 nearly plain ditopological spaces. Completions and real dicompactifications ... -

Ditopological Texture Spacesand Intuitionistic Sets
(Elsevier Science Bv, 1998)In this paper it is shown that the lattice of intuitionistic subsets of a set X in the sense of D. Coker may be represented as a special type of texture space, called an intuitionistic texture on X, and various characterizations ... -
Duo Modules
(Cambridge Univ Press, 2006)Let R be a ring. An R-module M is called a (weak) duo module provided every (direct summand) submodule of M is fully invariant. It is proved that if R is a commutative domain with field of fractions K then a torsion-free ... -
Effective Computation of Exact and Analytic Approximate Solutions to Singular Nonlinear Equations of Lane-Emden-Fowler Type
(Elsevier Science Inc, 2013)The particular motivation of this work is to develop a computational method to calculate exact and analytic approximate solutions to singular strongly nonlinear initial or boundary value problems of Lane-Emden-Fowler type ... -
Essential Spectra Of Quasi-Parabolic Composition Operators On Hardy Spaces Of The Poly-Disc
(Element, 2013)In this paper we study the essential spectra of a class of composition operators on the Hilbert-Hardy space of the hi-disc which is called "quasi-parabolic" and whose one variable analogue was studied in [2]. As in [2], ... -
Evaluation Of Spectrum Of 2-Periodic Tridiagonal-Sylvester Matrix
(Scientific Technical Research Council Turkey-Tubitak, 2016)The Sylvester matrix was first defined by JJ Sylvester. Some authors have studied the relationships between certain orthogonal polynomials and the determinant of the Sylvester matrix. Chu studied a generalization of the ... -
Existence Of A Global Attractor For The Parabolic Equation With Nonlinear Laplacian Principal Part In An Unbounded Domain

Existence Of A Global Attractor For The Plate Equation With A Critical Exponent In An Unbounded Domain
(Pergamon-Elsevier Science Ltd, 2005)In this work, we study the asymptotic behavior of solutions for the plate equation with a critical exponent in R-n. We prove the existence of a global attractor in W-2(2)(R-n) x L-2(R-n). (c) 2005 Elsevier Ltd. All rights ... -
Existence Of The Global Attractor For The Plate Equation With Nonlocal Nonlinearity In R-N
(Amer Inst Mathematical Sciences-Aims, 2016)We consider Cauchy problem for the semilinear plate equation with nonlocal nonlinearity. Under mild conditions on the damping coefficient, we prove that the semigroup generated by this problem possesses a global attractor. -
Exponential Attractors For Abstract Equations With Memory And Applications To Viscoelasticity
(Amer Inst Mathematical Sciences-Aims, 2015)We consider an abstract equation with memory of the form partial derivative(t)x(t) + integral(infinity)(0) k(s)Ax(t-s)ds + Bx(t) = 0 where A, B are operators acting on some Banach space, and the convolution kernel k is 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). ... -
Further Results On Fibre Products Of Kummer Covers And Curves With Many Points Over Finite Fields
(Amer Inst Mathematical Sciences-Aims, 2016)We study fibre products of an arbitrary number of Kummer covers of the projective line over F-q under suitable weak assumptions. If q - 1 = r(n) for some prime r, then we completely determine the number of rational points ... -
