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 ...
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 ...
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 ...
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 ...
Continuous Dependence Of Solutions To Fourth-Order Nonlinear Wave Equation
(Hacettepe Univ, Fac Sci, 2016)
This paper gives a priori estimates and continuous dependence of the solutions to fourth-order nonlinear wave equation.
A Coanalytic Menger Group That Is Not Sigma-Compact
(Scientific Technical Research Council Turkey-Tubitak, 2018)
Under V = L we construct coanalytic topological subgroups of reals, demonstrating that even for definable groups of reals, selection principles may differ.
Direct Sums And Summands Of Weak Cs-Modules And Continuous Modules
(Rocky Mt Math Consortium, 1999)
Interval Criteria for Oscillation of Second-Order Functional Differential Equations
(Pergamon-Elsevier Science Ltd, 2005)
By using averaging functions, new interval oscillation criteria are established for the second-order functional differential equation, (r (t) vertical bar x' (t)vertical bar(alpha-1) x' (t))' + F (t, x (t), x (tau (t)), ...
