On Mannheim partner curves in dual Lorentzian space
(Hacettepe Univ, Fac Sci, 2011)
In this paper we define non-null Mannheim partner curves in three dimensional dual Lorentzian space D(1)(3), and obtain necessary and sufficient conditions for the existence of non-null Mannheim partner curves in dual ...
Characterizations of the position vector of a surface curve in Euclidean 3-space
(Ovidius Univ Press, 2011)
In this paper, we give some characterizations of position vector of a unit speed curve in a regular surface M subset of E-3 which always lies in the planes spanned by {T, Z}, {T, Y} and {Y, Z}, respectively, by using ...
A Fixed point theorem on cone metric spaces with new type contractivity
(Duke Univ Press, 2011)
In the present work, a common fixed point theorem for self maps on cone metric spaces is proved. Also two examples, which shows that our main theorem is generalized version of main theorems of [A. Branciari, Int. J. Math. ...
Common fixed point theorems for weakly increasing mappings on ordered uniform spaces
(Univ Miskolc Inst Math, 2011)
In the present paper, we give a common fixed point theorem for two weakly increasing mappings on ordered Hausdorff uniform spaces, using the distance p: Two multivalued versions of this result are also presented.
An application of Ritt-Wu's zero decomposition algorithm to the pseudo null Bertrand type curves in Minkowski 3-space
(Springer Heidelberg, 2011)
The Bertrand curves were first studied using a computer by Wu (1987). The same problem was studied using an improved version of Ritt-Wu's decomposition algorithm by Chou and Gao (1993). This paper investigates the same ...
A Voronovskaya-type formula for SMK operators via statistical convergence
(Versita, 2011)
In this paper, we obtain a statistical Voronovskaya-type theorem for the Szasz-Mirakjan-Kantorovich (SMK) operators by using the notion of A-statistical convergence, where A is a non-negative regular summability matrix.
Dual Split Quaternions and Screw Motion in 3-Dimensional Lorentzian Space
(Birkhauser Verlag Ag, 2011)
In this paper we obtain screw axis of a displacement in L(3). Then by using the L-screw axis, L-Rodrigues equation for a spatial displacement is obtained in the space L(3). Moreover, the components of a dual split quaternion ...
Fixed point and homotopy results for multivalued maps satisfying an implicit relation
(Birkhauser Verlag Ag, 2011)
We present some common fixed point theorems for multivalued maps satisfying an implicit relation on complete metric spaces. Also a homotopy result is given for multivalued maps.
Some common fixed point theorems in vector metric spaces
(Univ Nis, Fac Sci Math, 2011)
In this paper we give some theorems on point of coincidence and common fixed points for two self mappings satisfying some general contractive conditions in vector metric spaces. Our results generalize some well-known recent ...
Expression of glutathione-S-transferases isoenzymes and p53 in exfoliated human bladder cancer cells
(Elsevier Science Inc, 2011)
Objectives: This study investigates the usefulness of glutathione-S-transferases (GST) isoenzymes and p53 immunostaining as a marker of malignancy in urinary cytology, and evaluates their potential effect in increasing ...
