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. ... -
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 ... -
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. -
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 ... -
Generalized q-Baskakov operators
(Walter De Gruyter Gmbh, 2011)In the present paper we propose a generalization of the Baskakov operators, based on q integers. We also estimate the rate of convergence in the weighted norm. In the last section, we study some shape preserving properties ... -
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 ... -
Dual Spaces Of Local Morrey-Type Spaces
(Springer Heidelberg, 2011)In this paper we show that associated spaces and dual spaces of the local Morrey-type spaces are so called complementary local Morrey-type spaces. Our method is based on an application of multidimensional reverse Hardy ... -
Some approximation properties of q-Baskakov-Durrmeyer operators
(Elsevier Science Inc, 2011)Very recently Aral and Gupta [1] introduced q analogue of Baskakov-Durrmeyer operators. In the present paper we extend the studies, we establish the recurrence relations for the central moments and obtain an asymptotic ... -
Approximation by q Baskakov Beta operators
(Springer Heidelberg, 2011)In the present paper we introduce the q analogue of the Baskakov Beta operators. We establish some direct results in the polynomial weighted space of continuous functions defined on the interval [0, a). Then we obtain ... -
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 ... -

(Springer Heidelberg, 2011)In this paper, we present some fixed point theorems for multivalued maps satisfying generalized phi-weak contractions on metric and ordered metric spaces. -
Characterizations of slant helices in Euclidean 3-space
(Scientific Technical Research Council Turkey-Tubitak, 2010)In this paper we investigate the relations between a general helix and a slant helix. Moreover, we obtain some differential equations which they are characterizations for a. space curve to be a slant helix. Also, we obtain ... -
Some Fixed Point Theorems on Ordered Metric Spaces and Application
(Springer International Publishing Ag, 2010)We present some fixed point results for nondecreasing and weakly increasing operators in a partially ordered metric space using implicit relations. Also we give an existence theorem for common solution of two integral equations. -
Ordered Non-Archimedean Fuzzy Metric Spaces and Some Fixed Point Results
(Springer, 2010)In the present paper we provide two different kinds of fixed point theorems on ordered nonArchimedean fuzzy metric spaces. First, two fixed point theorems are proved for fuzzy order phi-contractive type mappings. Then a ... -

On the Durrmeyer type modification of the q-Baskakov type operators
(Pergamon-Elsevier Science Ltd, 2010)This paper deals with Durrmeyer type generalization of q-Baskakov type operators using the concept of q-integral, which introduces a new sequence of positive q-integral operators. We show that this sequence is an approximation ... -
