  • Zeynep Ketenci; Tulay Erisir; Güngör, Mehmet Ali (TAYLOR & FRANCIS LTD, 2015)
    In this paper, spinors which consists of two hyperbolic components are introduced and hyperbolic spinor representation of the curve (spacelike or timelike) in Minkowski space is expressed. Then, the fundamental theorem of ...
  • Altıntaş, İsmet; Kemal Taskopru (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2018)
    In this paper, we define the delta derivative in the integer group ring and we show that the delta derivative is well defined on the free groups. We also define a polynomial invariant of oriented knot and link by carrying ...
  • Özdemir, Halim (ELSEVIER SCIENCE INC, 2004)
    The purpose of this note is to characterize all situations in which a linear combination of two commuting tripotent matrices is also a tripotent matrix. In the case of real scalars and real symmetric matrices, this problem ...
  • Keskin, Refik; Merve Guney Duman (UNIV MISKOLC INST MATH, 2017)
    Let k >= 3 be an odd integer. In this paper we investigate all positive integer solutions of the equations x(4) - kx(2) y + y(2) = -/+ A, x(4) kx(2) y + y(2) = -/+ A(k(2) - 4), x(4) - (k(2) - 4)y(2) = -/+ 4A, and x(2) - ...
  • Keskin, Refik (SPRINGER, 2005)
    In this paper, we introduce some Fuchsian groups and calculate their parabolic class numbers. In addition, we give two conjectures concerning with the parabolic class number.
  • Keskin, Refik (WORLD SCIENTIFIC PUBL CO PTE LTD, 2003)
    In this paper, we introduce some discrete subgroups of PSL(2, C) and determine the number of cusps of 3-manifolds associated to those groups.
  • Halıcı, Serpil (SPRINGER INTERNATIONAL PUBLISHING AG, 2013)
    We give some fundamental properties related to them. Also, we obtain asymptotic results for the roots of polynomials G(n)((k))(X).
  • Yılmaz, Yalçın; Yılmaz, Yücel (PERGAMON-ELSEVIER SCIENCE LTD, 2007)
    We obtained the spatial growth and decay estimates for solutions of a class of quasilinear equations modelling dynamic viscoelasticity in a domain Omega x (0, T), where Omega subset of R-n is a semi-infinite cylinder. (C) ...

    In this study, the dual-hyperbolic Fibonacci and dual-hyperbolic Lucas numbers are introduced. Then, the fundamental identities are proven for these numbers. Additionally, we give the identities regarding negadual-hyperbolic ...
  • 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)).
  • Yılmaz, Yalçın (ELSEVIER SCIENCE INC, 2012)
    Active vibration control in a flexible beam is investigated by taking into account the time-delay which may occur in voltage controlled piezoelectric actuators. The voltage applied to a piezoelectric patch actuator to ...
  • 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 ...

    In this study, we have considered the elliptical harmonic motion which is the superposition of two simple harmonic motions in perpendicular directions with the same angular frequency and phase difference of pi/2. It is ...
  • Özen, Mehmet (PERGAMON-ELSEVIER SCIENCE LTD, 2007)
    We investigate the structure of codes over Galois rings with respect to the Rosenbloom-Tsfasman (shortly RT) metric. We define a standard form generator matrix and show how we can determine the minimum distance of a code ...
