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 DiracDelta Distribution For Negative Integers
(PergamonElsevier Science Ltd, 2001)In [1], Koh and Kuan defined the powers of the Diracdelta distribution for positive integers. Here we extend their definition for negative integers. Also, we give meaning to the distribution delta (kappa)(+). (C) 2001 ... 
DiExtremities And Totally Bounded DiUniformities
(Univ Nis, Fac Sci Math, 2018)In our previous studies, we have defined a counterpart, called a diextremity, to the classical notion proximity in the complementfree setting of a texture. In this article, we will investigate relationship between totally ... 
DiUniformities and Hutton Uniformities
(Elsevier Science Bv, 2012)The authors characterize diuniformities on a texture (S, J) in the sense of Ozgag and Brown (Diuniform texture spaces, Appl. Gen. Top. 4(1) (2003), 157192) 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 biT2 nearly plain ditopological spaces. Completions and real dicompactifications ... 
Direct Sums And Summands Of Weak CsModules And Continuous Modules
(Rocky Mt Math Consortium, 1999) 
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 Rmodule 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 torsionfree ... 
Effective Computation of Exact and Analytic Approximate Solutions to Singular Nonlinear Equations of LaneEmdenFowler 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 LaneEmdenFowler type ... 
Essential Spectra Of QuasiParabolic Composition Operators On Hardy Spaces Of The PolyDisc
(Element, 2013)In this paper we study the essential spectra of a class of composition operators on the HilbertHardy space of the hidisc which is called "quasiparabolic" and whose one variable analogue was studied in [2]. As in [2], ... 
Evaluation Of Spectrum Of 2Periodic TridiagonalSylvester Matrix
(Scientific Technical Research Council TurkeyTubitak, 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
(Academic Press Inc Elsevier Science, 2006) 
Existence Of A Global Attractor For The Plate Equation With A Critical Exponent In An Unbounded Domain
(PergamonElsevier Science Ltd, 2005)In this work, we study the asymptotic behavior of solutions for the plate equation with a critical exponent in Rn. We prove the existence of a global attractor in W2(2)(Rn) x L2(Rn). (c) 2005 Elsevier Ltd. All rights ... 
Existence Of The Global Attractor For The Plate Equation With Nonlocal Nonlinearity In RN
(Amer Inst Mathematical SciencesAims, 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 SciencesAims, 2015)We consider an abstract equation with memory of the form partial derivative(t)x(t) + integral(infinity)(0) k(s)Ax(ts)ds + Bx(t) = 0 where A, B are operators acting on some Banach space, and the convolution kernel k is a ... 
FiniteDimensional Attractors For A General Class Of Nonautonomous Wave Equations
(PergamonElsevier 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
(PergamonElsevier 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 SciencesAims, 2016)We study fibre products of an arbitrary number of Kummer covers of the projective line over Fq under suitable weak assumptions. If q  1 = r(n) for some prime r, then we completely determine the number of rational points ...
