    • An Extension of the Incomplete Beta Function For Negative Integers 

      Özcağ, Emin; Ege, İnci; Gürçay, Haşmet (Academic Press Inc Elsevier Science, 2008)
      The incomplete beta function B-x(a, b) is defined for a, b > 0 and 0 < x < 1. Its definition can be extended, by regularization, to negative non-integer values of a and b. In this paper we define the incomplete beta function ...

    • An Optimal Variational Iteration Method 

      Türkyılmazoğlu, M. (Pergamon-Elsevier Science Ltd, 2011)
      The variational iteration method is studied in the present work. The classical variational iteration method is improved and extended by introducing a new concept of a convergence accelerating parameter. A rigorous approach ...

    • Asymptotic Behaviour of a Class of Nonlinear Functional Differential Equations of Third Order 

      Tiryaki, A; Yaman, S (Pergamon-Elsevier Science Ltd, 2001)
      This paper deals with nonoscillatory behaviour of solutions of third-order nonlinear functional differential equations of the form y''' + p(t)y' + q(t)F(y(g(t))) = 0. It has been shown that under certain conditions on ...

    • Asymptotic Calculation of Inviscidly Absolutely Unstable Modes of the Compressible Boundary Layer on a Rotating Disk 

      Turkyilmazoglu, M (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 

      Erdem, D (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 ...

    • Categories of Rough Sets and Textures 

      Diker, Murat (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 

      Yildiz, Filiz (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 

      Kalafat, Mustafa; Arguez, Huelya (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

      This paper gives a priori estimates and continuous dependence of the solutions to fourth-order nonlinear wave equation.

    • Definability And Textures 

      Diker, Murat (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 

      Ozcag, E (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 ...
