BlowUp of Solutions to Quasilinear Parabolic Equations
(PergamonElsevier Science Ltd, 1999)Sufficient conditions for global nonexistence (blow up) of solutions of the initialboundary value problem for a class of secondorder quasilinear parabolic equations: [GRAPHICS] are established. (C) 1999 Elsevier Science ... 
Categories of Rough Sets and Textures
(Elsevier Science Bv, 2013)It is known that the theories of rough sets and fuzzy sets have successful applications in computing. Textures, as a theoretical model, provide a new perspective for both rough sets and fuzzy sets. Indeed, recent papers ... 
Completeness Types For Uniformity Theory On Textures
(Univ Nis, Fac Sci Math, 2015)In this paper the author considers the various types of completeness for diuniform texture spaces and especially for complemented ones. Following that, the relationships between completeness of uniform spaces and these ... 
Complex And Symplectic Structures On Panelled Web 4Manifolds
(Elsevier Science Bv, 2012)We analyze the symplectic and complex structures on the panelled web 4manifolds of S. Akbulut and M. Kalafat [1]. In particular, we give infinite families of examples of almost complex but not symplectic and not complex ... 
Continuous Dependence Of Solutions To FourthOrder Nonlinear Wave Equation
(Hacettepe Univ, Fac Sci, 2016)This paper gives a priori estimates and continuous dependence of the solutions to fourthorder nonlinear wave equation. 
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 ...
