Asymptotic Calculation of Inviscidly Absolutely Unstable Modes of the Compressible Boundary Layer on a Rotating Disk
(Pergamon-Elsevier Science Ltd, 2006)In this work a long-wavelength asymptotic approach is used to analyze the region of absolute instability in the compressible rotating disk boundary layer flow. Theoretically determined values of branch points for the ... -
Blow-Up of Solutions to Quasilinear Parabolic Equations
(Pergamon-Elsevier Science Ltd, 1999)Sufficient conditions for global nonexistence (blow up) of solutions of the initial-boundary value problem for a class of second-order quasilinear parabolic equations: [GRAPHICS] are established. (C) 1999 Elsevier Science ... -
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 di-uniform 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 4-Manifolds
(Elsevier Science Bv, 2012)We analyze the symplectic and complex structures on the panelled web 4-manifolds 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 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. -
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 ... -
