  • THE SQUARE TERMS IN GENERALIZED LUCAS SEQUENCES 
    Keskin, Refik (LONDON MATH SOC, 2014)
    Let P and Q be non-zero integers. The generalized Fibonacci sequence {U-n} and Lucas sequence {V-n} are defined by U-0 = 0, U-1 = 1 and Un+1 = PUn + QU(n-1) for n >= 1 and V-0 = 2, V-1 = P and Vn+1 = PVn + QV(n-1) for n ...
  • The MacWilliams identity for m-spotty Rosenbloom-Tsfasman weight enumerator 
    Şiap, Vedat (PERGAMON-ELSEVIER SCIENCE LTD, 2014)
    The communication systems and disk or tape memory can sometimes cause clusters of errors, namely burst errors. There have been many designs in order to detect and even correct such errors. Recently, a new class of codes ...
  • Generalized Fibonacci and Lucas numbers of the form 5x(2) 
    Keskin, Refik; Karaatlı, Olcay (WORLD SCIENTIFIC PUBL CO PTE LTD, 2015)
    Let (U-n(P, Q) and (V-n(P, Q) denote the generalized Fibonacci and Lucas sequences, respectively. In this study, we assume that Q = 1. We determine all indices n such that U-n = 5 square and U-n = 5U(m)square under some ...
  • AN IDENTITY BETWEEN THE m-SPOTTY ROSENBLOOM-TSFASMAN WEIGHT ENUMERATORS OVER FINITE COMMUTATIVE FROBENIUS RINGS 
    Özen, Mehmet; Minjia Shi; Vedat Siap (KOREAN MATHEMATICAL SOC, 2015)
    This paper is devoted to presenting a MacWilliams type identity for m-spotty RT weight enumerators of byte error control codes over finite commutative Frobenius rings, which can be used to determine the error-detecting and ...
  • GENERALIZED SPACELIKE BERTRAND CURVES IN MINKOWSKI 5-SPACE R-1(5) 
    Ersoy, Soley (NATL INQUIRY SERVICES CENTRE PTY LTD, 2014)
    In this paper, we give the definition of the generalization of spacelike Bertrand curves and obtain the characterization of these curves in Minkowski 5-space R-1(5). Moreover, we define three types special spacelike Bertrand ...
  • Travelling Wave Solutions for the Coupled IBq Equations by Using the tanh-coth Method 
    Gözükızıl, Ömer Faruk (HINDAWI PUBLISHING CORPORATION, 2014)
    Based on the availability of symbolic computation, the tanh-coth method is used to obtain a number of travelling wave solutions for several coupled improved Boussinesq equations. The abundant new solutions can be seen as ...
  • Lacunary Delta-statistical convergence in intuitionistic fuzzy n-normed space 
    Altundağ, Selma (SPRINGEROPEN, 2014)
    The concept of lacunary statistical convergence was introduced in intuitionistic fuzzy n-normed spaces in Sen and Debnath (Math. Comput. Model. 54: 2978-2985, 2011). In this article, we introduce the notion of lacunary ...
  • On some new sequence spaces of fuzzy numbers 
    Başarır, Metin (INDIAN NAT SCI ACAD, 2003)
    In this paper, we introduce and study some new sequence spaces of fuzzy numbers generated by non-negative regular matrix A = (a(nk)) (n, k = 1, 2).
  • A. note on some modular subgroups 
    Keskin, Refik (ROCKY MT MATH CONSORTIUM, 2005)
    In this study, we introduce some modular subgroups and we calculate parabolic class numbers of those groups. In addition to this, we gave a nice formula for the parabolic class number of Gamma(0)(n(2)).
  • Perfect Mannheim, Lipschitz and Hurwitz weight codes 
    Güzeltepe, Murat (UNIV OSIJEK, DEPT MATHEMATICS, 2014)
    The set of residue classes modulo an element pi in the rings of Gaussian integers, Lipschitz integers and Hurwitz integers, respectively, is used as alphabets to form the words of error correcting codes. An error occurs ...
  • On some fixed-point theorems for psi-contraction on metric space involving a graph 
    Öztürk, Mahpeyker (SPRINGEROPEN, 2014)
    In this paper, we introduce the (G,psi)-contraction and the (G,psi)-graphic contraction in a metric space by using a graph. We explain some conditions for a mapping which is a (G,psi)-contraction to have a unique fixed ...
