Degenerate spin structures and the Levy-Leblond equation
(2006)Newton-Cartan manifolds and the Galilei group are defined by the use of co-rank one degenerate metric tensor. Newton-Cartan connection is lifted to the degenerate spinor bundle over a Newton-Cartan 4-manifold by the aid ... -

Dependence on the parameters of the set of trajectories of the control system described by a nonlinear Volterra integral equation
(Acad Sciences Czech Republic, Inst Mathematics, 2014)In this paper the control system with limited control resources is studied, where the behavior of the system is described by a nonlinear Volterra integral equation. The admissible control functions are chosen from the ... -
Derivatives of the restrictions of harmonic functions on the Sierpinski gasket to segments
(Academic Press Inc Elsevier Science, 2007)We give an explicit derivative computation for the restriction of a harmonic function on SG to segments at specific points of the segments: The derivative is zero at points dividing the segment in ratio 1:3. This shows ... -
Development of a three dimensional geometric thinking test for early graders
(Sriwijaya University, 2018)This study aimed to develop a three-dimensional geometric thinking test to determine the geometric thinking of early graders in the paper-pencil environment. First, we determined the components of three-dimensional geometric ... -
Dirac Operator on a 7-Manifold with Deformed G(2) Structure
(Ovidius University Press, 2012)In this work, we consider the deforming of a G(2) structure by a vector field on a 7-manifold. To obtain the metric corresponding to deformed G(2) structure, a new map is defined. By using this new map, the co-variant ... -
Directional convex extensions of the convex valued maps
(2009)In this paper, the concept of directional convex extension of the convex valued maps is introduced. Necessary and sufficient conditions for the existence of the directional convex extension of the convex valued map are obtained -
Effects of shear stress forces to rotordynamic coefficients in staggered labyrinth seals
(Professional Engineering Publishing LTD, 2006)In this article, shear stresses in calculating the rotordynamic coefficients of staggered labyrinth seals are presented. Differences in the values of these coefficients are observed and quantified. The results of the present ... -
An equivalence class decomposition of finite metric spaces via Gromov products
(Elsevier Science BV, 2017)Let (X, d) be a finite metric space with elements P-i, i = 1,..., n and with the distance functions d(ij) The Gromov Product of the "triangle" (P-i, P-j, P-k) with vertices P-t, P-j and P-k at the vertex Pi is defined by ... -
An estimate of the oscillation of harmonic reproducing kernels with applications
(Academic Press Inc Elsevier Science, 2016)We estimate the oscillation of harmonic reproducing kernels. As an application of this estimation we obtain a double integral characterization of harmonic Besov spaces -
Euclidean realizations of Mauldin-Williams graphs
(2013)Graph-directed fractals are collections of metric spaces, each of which can be expressed as a union of several scaled copies of spaces from the collection. They give rise to weighted, directed graphs where the term comes ... -
The Euler characteristic and signature of four-dimensional closed manifolds and the normalized Ricci flow equation
(Springer, 2016)Let M be a closed manifold of dimension four, and let [0, T) be the maximal time interval for the normalized Ricci flow equation. We prove that, if the normalized Ricci flow equation has a solution on the non-negative real ... -
Evaluation of 11th grade students' cognitive behaviour on some subjects of analysis according to gender
(2005)The purpose of this research is to investigate students' cognitive behaviour in the subjects of function, limit, and derivative according to gender. The research was conducted with the participation of 67 female and 58 ... -

Existence of a dense orbit and topological transitivity: When are they equivalent?
(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 ... -
