Spaces of skew-symmetric matrices satisfying A(3) = lambda A
Özdemir, Yunus (Elsevier Science Inc, 2013)We calculate the maximum dimension of a space of m x m real skew-symmetric matrices of corank 1 satisfying A(3) = lambda(A)A for some real lambda(A) > 0 -
Spinors on Kahler-Norden manifolds
Değirmenci, Nedim; Bulut, Şenay (2010)It is known that the complex spin group Spin(n,C) is the universal covering group of complex orthogonal group SO(n,C). In this work we construct a new kind of spinors on some classes of Kahler-Norden manifolds. The structure ... -
SpinT structure and dirac operator on riemannian manifolds
Bulut, S.; Erkoca, A. K. (Balkan Society of Geometers, 2018)In this paper, we describe the group SpinT (n) and give some properties of this group. We construct SpinT spinor bundle S[double-struck] by means of the spinor representation of the group SpinT (n) and define covariant ... -
Stabilisation of discrete-time systems via Schur stability region
Büyükköroğlu, Taner; Çelebi, Gökhan; Dzhafarov, Vakif (Taylor & Francis LTD, 2018)In this paper, we consider the stabilisation problem of discrete-time systems by affine compensator. Using the known properties of the Schur stability region of monic polynomials, we give conditions under which stabilising ... -
Stability of Graphs
Demir, Bünyamin; Deniz, Ali; Koçak, Şahin (Electronic Journal Of Combinatorics, 2009)Positively weighted graphs have a natural intrinsic metric. We consider finite, positively weighted graphs with a positive lower bound for their minimal weights and show that any two such graphs, which are close enough ... -
Stabilization of Discrete Systems with Bounded Parameters
Büyükköroğlu, Taner; Dzhafarov, Vakif (2017)In this paper stabilization problem of linear discrete single input, single output plant by affine stabilizator is considered. It is assumed that stabilizing vector is bounded and its values are changed in a given box. We ... -
Stabilization of Discrete Time Systems By Reflection Coefficients
Büyükköroğlu, Taner; Çelebi, Gökhan; Dzhafarov, Vakif (Krasovskii Inst Mathematics & Mechanics Ural Branch Russian Acad Sciences, 2017)For single-input single-output discrete-time systems, we consider a stabilization problem by a fixed order controller. A number of examples show that such controller may not exist. It is assumed that the controller depends ... -
Strong 2-Calibrations on R-2N
Koçak, Şahin; Özdemir, Yunus (Kinokuniya Co LTD, 2011)Most of the classical calibrations possess a property which does not seem to be recognized. Making this property explicit, we define what we call the strong calibrations and prove that a strong 2-calibration field on R-2n ... -

Students' interpretation of a function associated with a real-life problem from its graph
Mahir, Nevin (2010)The properties of a function such as limit, continuity, derivative, growth, or concavity can be determined more easily from its graph than by doing any algebraic operation. For this reason, it is important for students of ... -
Students' misconceptions and errors in transformation geometry
Ada, Tuba; Kurtuluş, Aytaç (2010)This study analyses the students' performances in two-dimensional transformation geometry and explores the mistakes made by the students taking the analytic geometry course given by researchers. An examination was given ... -
Super and strongly faintly continuous multifunctions
Zorlutuna, I.; Küçük, Y. (2001)In this paper, we introduce and discuss some strong forms of faintly continuity for multifunctions. Basic properties and characterizations of such multifunctions are established. -

Three different methods for numerical solution of the EW equation
Saka, Bülent; Dağ, İdris; Dereli, Yılmaz; Korkmaz, Alper (Elsevier Sci LTD, 2008)Numerical solutions of the equal width wave (EW) equation are obtained by using a Galerkin method with quartic B-spline finite elements, a differential quadrature method with cosine expansion basis and a meshless method ... -
Tight span of subsets of the plane with the maximum metric
Kılıç, Mehmet; Koçak, Şahin (Academic Press Inc Elsevier Science, 2016)We prove that a nonempty closed and geodesically convex subset of the l(infinity) plane R-infinity(2) is hyperconvex and we characterize the tight spans of arbitrary subsets of R-infinity(2) via this property: Given any ... -
Transfer Skills of Middle School Pre-service Mathematics Teachers from Informal to Formal Mathematical Language: Turkey and United States Cases
Uygur-Kabael, Tangül (Hacettepe University, 2017)Mathematics, as universal language, is used by individuals with different native in a way that is influenced by their native languages. Two kinds of uses, formal and informal, of mathematical language arise since the ... -
Tube Formulas for Graph-Directed Fractals
Demir, Bünyamin; Deniz, Ali; Koçak, Şahin; Üreyen, Adem Ersin (World Scientific Publ Co Pte LTD, 2010)Lapidus and Pearse proved recently an interesting formula about the volume of tubular neighborhoods of fractal sprays, including the self-similar fractals.
