Constancy of maps into f-manifolds and pseudo f-manifolds
(2007)Constancy of some maps into certain f-manifolds and pseudo f-manifolds is discussed. As a result a Constancy Theorem is given, for maps of Riemannian manifolds into these manifolds, which recovers all the results obtained so far -
Affine contractions on the plane
(2007)Contractions play a considerable role in the theory of fractals. However, it is not easy to find contractions which are not similitudes. In this study, it is shown by counter examples that an affine transformation of the ... -
Degenerate spin structures and the Lévy-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 ... -
A classification of points on the Sierpinski gasket
(2008)In this article we classified the points of the well-known fractal set Sicrpinski Gasket (SG) according to their addresses. We also gave a characterization of points of SG that describes the relation between their addresses ... -
Spinors on Kahler-Norden manifolds
(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 ... -
A note on families of stable matrices
(2010)In this paper, some properties of families of stable matrices are studied. It is shown that various families of stable matrices are contractible, and as a consequence these families are simply-connected. -
The ability of students to comprehend the function-derivative relationship with regard to problems from their real life
(2009)This study investigated whether students who are studying calculus were able to determine the graph of the derivative of the functions related to the problems they come across in their daily lives or in applied science. A ... -
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 -
On generalizations of extending modules
(Kyungpook National University, 2009)A module M is said to be SIP-extending if the intersection of every pair of direct summands is essential in a direct summand of M. SIP-extending modules are a proper generalization of both SIP-modules and extending modules. ... -
Students' interpretation of a function associated with a real-life problem from its graph
(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 ... -
Self-dual gauge fields in eight dimensions
(1997)Self-dual gauge fields in even dimensional spaces are characterised by a set of constraints on the eigenvalues of F. We derive a new topological bound (Latin small letter esh sign)M(F, F)2 ? ?M P12 on a compact 8-manifold ... -
Students' misconceptions and errors in transformation geometry
(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 ... -
Some fixed point theorems for set-valued mappings in uniform spaces
(Walter de Gruyter GmbH, 1999)[No abstract available] -
?-blocking and hysteresis in the EEG
(1995)We investigated the phenomenon of ?-blocking by using a smoothly changing illumination as the visual stimulus and showed that there is no increase of ß-waves during ?-blocking. We were unable to see any form of ?-ß competition ... -
Monopole Equations on R8: The Energy Integral
(2000)We discuss the Seiberg-Witten theory in four dimensions and possible generalizations to eight dimensions. We propose an action which is minimized by a set of monopole equations, previously obtained as a generalization of ... -
The common vector approach and its relation to principal component analysis
(2001)The main point of the paper is to show the close relation between the nonzero principal components and the difference subspace together with the complementary close relation between the zero principal components and the ... -
On unified theory for continuities
(2002)The purpose of this study is to give a unified theory for some weak and strong continuous functions using operations -
Super and strongly faintly continuous multifunctions
(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. -
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 ...
