The Bochner technique and modification of the Ricci tensor
(Springer, 2009)In the well-known vanishing theorems of Bochner, the assumptions Ric a parts per thousand yen 0 and Ric a parts per thousand currency sign 0 are modified by using Hessian and Laplacian of a smooth positive function such ... -
The Bakry-Emery Ricci tensor and its applications to some compactness theorems
(Springer, 2012)Let (M, g) be a complete and connected Riemannian manifold of dimension n. By using the Bakry-Emery Ricci curvature tensor on M, we prove two theorems which correspond to the Myers compactness theorem. -
Transfer Skills of Middle School Pre-service Mathematics Teachers from Informal to Formal Mathematical Language: Turkey and United States Cases
(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 ... -
Inclusion relations between harmonic Bergman-Besov and weighted Bloch spaces on the unit ball
(Springer Heidelberg, 2019)We consider harmonic Bergman-Besov spaces bp and weighted Bloch spaces b on the unit ball of (n) for the full ranges of parameters 0 < p < , , and determine the precise inclusion relations among them. To verify these ... -
Seiberg-Witten Equations on 8-Dimensional Manifolds With Su(4)-Structure
(World Scientific Publ Co Pte LTD, 2013)Seiberg-Witten equations on 8-manifolds with Spin(7)-holonomy are introduced in [A. H. Bilge, T. Dereli and S. Kocak, Monopole equations on 8-manifolds with Spin(7) holonomy, Commun. Math. Phys. 203(1) (1999) 21-30] and ... -
Radial basis functions method for numerical solution of the modified equal width equation
(Taylor & Francis LTD, 2010)The numerical solution of the modified equal width equation is investigated by using meshless method based on collocation with the well-known radial basis functions. Single solitary wave motion, two solitary waves interaction ... -
On the stability of a convex set of matrices
(Elsevier Science Inc, 2006)In this paper we give an alternative proof of the constant inertia theorem for convex compact sets of complex matrices. It is shown that the companion matrix whose non-trivial column is negative satisfies the directional ... -
On the Compactness of the Attainable Sets of Control Systems With P-Integrable Controls
(University Miskolc Inst Math, 2008)Quasi-linear systems governed by p-integrable controls, for 1 < p < infinity with the constraint parallel to u parallel to(p) <= mu(0) are studied. It is proved that the attainable sets of the system at the instant of time ... -
Linear Functions and Slope: How Do Students Understand These Concepts and How Does Reasoning Support Their Understanding?
(Fac Teacher Education, 2018)The aim of this study was to investigate eighth grade students' conceptual understanding and types of reasoning about linear functions and slope. This is a mixed method study. Quantitative data were collected with algebra ... -
Harmonic Besov spaces on the ball
(World Scientific Publ Co Pte LTD, 2016)We initiate a detailed study of two-parameter Besov spaces on the unit ball of R-n consisting of harmonic functions whose sufficiently high-order radial derivatives lie in harmonic Bergman spaces. We compute the reproducing ... -
Weighted Harmonic Bloch Spaces on the Ball
(Springer Basel Ag, 2018)We study the family of weighted harmonic Bloch spaces , on the unit ball of . We provide characterizations in terms of partial and radial derivatives and certain radial differential operators that are more compatible with ... -
Precise inclusion relations among Bergman-Besov and Bloch-Lipschitz spaces and H infinity on the unit ball of C-N
(Wiley-V C H Verlag GMBH, 2018)We describe exactly and fully which of the spaces of holomorphic functions in the title are included in which others. We provide either new results or new proofs. More importantly, we construct explicit functions in each ... -
Oscillation of holomorphic Bergman-Besov kernels on the ball
(Springer Wien, 2017)We estimate the oscillation of holomorphic Bergman-Besov reproducing kernels on the unit ball of . As an application of this estimate we characterize holomorphic Bergman-Besov spaces in terms of double integrals of the ... -
Reproducing kernels for harmonic Besov spaces on the ball
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2009)Besov spaces of harmonic functions on the unit ball of R '' are defined by requiring Sufficiently high-order derivatives of functions lie in harmonic Bergman spaces. We compute the reproducing kernels of those Besov spaces ... -
Intrinsic Metrics on Sierpinski-Like Triangles and Their Geometric Properties
(MDPI, 2018)The classical Sierpinski Gasket defined on the equilateral triangle is a typical example of fractals. Sierpinski-like triangles can also be constructed on isosceles or scalene triangles. An explicit formula for the intrinsic ... -
Modules Whose Submodules Are Essentially Embedded in Direct Summands
(Taylor & Francis Inc, 2009)A module M is said to satisfy the C-12 condition if every submodule of M is essentially embedded in a direct summand of M. It is known that the C-11 ( and hence also C-1) condition implies the C-12 condition. We show that ... -
An explicit formula of the intrinsic metric on the Sierpinski gasket via code representation
(Scientific Technical Research Council Turkey-Tubitak, 2018)The computation of the distance between any two points of the Sierpinski gasket with respect to the intrinsic metric has already been investigated by several authors. However, to the best of our knowledge, in the literature ... -
On matrix rings with the SIP and the Ads
(Scientific Technical Research Council Turkey-Tubitak, 2018)In this paper, matrix rings with the summand intersection property (SIP) and the absolute direct summand (ads) property (briefly, SA) are studied. A ring R has the right SIP if the intersection of two direct summands of R ... -
Some Interesting Code Sets of the Sierpinski Triangle Equipped with the Intrinsic Metric
(Centre Environment Social & Economic Research Publ-Ceser, 2018)Many different characteristics of the Sierpinski triangle, which is one of the most popular examples of fractals, have been the subject of research for various studies in the recent years. To define the intrinsic metric ... -
On Some Finite Hyperbolic Spaces
(Charles Babbage Res Ctr, 2012)Let pi be a finite projective plane of order n. Consider the substructure pi(n+2) obtained from pi by removing n + 2 lines (including all points on them) no three are concurrent. In this paper, firstly, it is shown that ...
