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 ... -
DEĞİŞMELİ OLMAYAN HALKALARDA COHEN VE KAPLANSKY TEOREMLERİNİN GENELLEMELERİ
(Fen Bilimleri Enstitüsü, 2017-08)In commutative setting, prime ideals are very important tools to determine the structure of a ring. In this thesis, some structure theorems will be discussed which belong to Cohen and Kaplansky. The aim of this thesis ... -
Derivations and Automorphisms of Certain Subrings of Matrix Rings
(Fen Bilimleri Enstitüsü, 2018)Let K be an arbitrary associative ring with identity. We denote by Mn(K) the ring of all nxn matrices over K. Say K=F for some field F. Then it is a consequence of Skolem-Noether theorem that every automorphism of Mn(F) ... -
Derivations and Automorphisms of Some Infinite Matrix Algebras
(Fen Bilimleri Enstitüsü, 2021)Let R be a commutative ring with identity and M_n(R) be the algebra (ring) of all n x n matrices over R. Note that an additive D of a ring R into itself is said to be a derivation of R if D(xy)=D(x)y+xD(y) for all x, y ... -
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 ... -
Diçatılara Genelleştirilmiş Bazı Topolojik Kavramlar
(Fen Bilimleri Enstitüsü, 2018)The aim of this thesis is to define the notion of diframe as a generalization of ditopological texture spaces and to study the topological concepts such as separation axioms and compactness in diframe setting. This work ... -

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 ... -
Endomorfizma Halkası Düzenli Olan Modüller Üzerine Bir Çalışma
(Fen Bilimleri Enstitüsü, 2022-06-22)In the first part of our thesis, a brief information about the studies on regular rings is given. In the second chapter, the general properties of regular and unit regular rings, and some basic concepts that we will use ... -
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 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 ...
