Chaos in product maps
Değirmenci, Nedim; Koçak, Şahin (Scientific Technical Research Council Turkey-Tubitak, 2010)We discuss how chaos conditions on maps carry over to their products First we give a counterexample showing that the product of two chaotic maps (in the sense of Devaney) need not be chaotic We then remark that if two maps ... -
The construction of maximum independent set of matrices via Clifford algebras
Değirmenci, Nedim; Özdemir, Nülifer (Scientific Technical Research Council Turkey-Tubitak, 2007)In [1], [2] and [6] the maximum number of some special type n x n matrices with elements in F whose nontrivial linear combinations with real coefficients are nonsingular is studied where F is the real field R, the complex ... -
Existence of a dense orbit and topological transitivity: When are they equivalent?
Değirmenci, Nedim; Koçak, Şahin (Akademiai Kiado, 2003)Topological transitivity and existence of a dense orbit are two notions which play an important role in every definition of chaos [2], [4]. Unfortunately, in the literature there are often misunderstandings (or even false ... -
Schrodinger-Lichnerowicz Like Formula on Kahler-Norden Manifolds
Değirmenci, Nedim; Bulut, Şenay (World Scientific Publ Co Pte LTD, 2012)A new kind of spinors and Dirac operator are introduced on Kahler-Norden manifolds in [Spinors on Kahler-Norden manifolds, J. Nonlinear Math. Phys. 17(1) (2010) 27-34]. In this work the square D-2 of the Dirac operator D ... -
Seiberg-Witten Equations on Four-Dimensional Lorentzian Spin(C) Manifolds
Değirmenci, Nedim; Özdemir, Nülifer (World Scientific Publ Co Pte LTD, 2011)New kind of spinors are introduced on four-dimensional Lorentzian Spin(c) manifolds in [1]. We define Dirac operator on such spinors. In [2] Seiberg-Witten-like equations are written down on Minkowski space. In the present ... -
Seiberg-Witten equations on pseudo-Riemannian spinc manifolds with neutral signature
Değirmenci, Nedim; Bulut, Şenay (Ovidius University, 2012)Pseudo-Riemannian spinc manifolds were introduced by Ikemakhen in [7]. In the present work we consider pseudoRiemannian 4-manifolds with neutral signature whose structure groups are SO+(2; 2). We prove that such manifolds ... -
Seiberg-Witten Like Equations on Pseudo-Riemannian Spin.. Manifolds with G(2(2))* Structure
Özdemir, Nülifer; Değirmenci, Nedim (Hindawi LTD, 2016)We consider 7-dimensional pseudo-Riemannian spin(c) manifolds with structure group G(2(2))*. On such manifolds, the space of 2-forms splits orthogonally into components Lambda M-2 = Lambda(2)(7) circle plus Lambda(2)(14). ... -
Seiberg-Witten-like equations on 5-dimensional contact metric manifolds
Değirmenci, Nedim; Bulut, Şenay (Scientific Technical Research Council Turkey-Tubitak, 2014)In this paper, we write Seiberg-Witten-like equations on contact metric manifolds of dimension 5. Since any contact metric manifold has a Spin(e)-structure, we use the generalized Tanaka-Webster connection on a Spin(e) ... -
Seiberg-Witten-like equations on 6-dimensional SU(3)-manifolds
Değirmenci, Nedim; Bulut, Şenay (Balkan Society of Geometers, 2015)It is known that Seiberg-Witten monopole equations are important for the investigations of smooth 4-manifolds. In this study we write the similar equations for 6-dimensional manifold M with structure group SU(3). For Dirac ... -
Seiberg-Witten-like equations on 7-manifolds with G(2)-structure
Değirmenci, Nedim; Özdemir, N (Norbert Euler, 2005)The Seiberg-Witten equations are of great importance in the study of topology of smooth four-dimensional manifolds. In this work, we propose similar equations for 7-dimensional compact manifolds with G(2)-structure. -
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 ...
