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 ... -
