Semi-Parallel Tensor Product Surfaces In Semi-Euclidean Space E4 2
(2016)In this article, the tensor product surfaces are studied that arisefrom taking the tensor product of a unit circle centered at the origin in Euclidean plane E2and a non-null, unit planar curve in Lorentzian plane E1. Also ... -
Simultaneous Approximation for Generalized Srivastava-Gupta Operators
(Hindawi Ltd, 2015)We introduce a new Stancu type generalization of Srivastava-Gupta operators to approximate integrable functions on the interval (0, infinity) and estimate the rate of convergence for functions having derivatives of bounded ... -
Simultaneous approximation with generalized Durrmeyer operators
(Elsevier Science Inc, 2015)The aim of this paper is to obtain some convergence properties of generalized sequences of Ibragimov-Gadjiev-Durrmeyer operators which are a wide class of linear positive operators including many well known linear positive ... -
Some Approximation Properties Of Kantorovich Variant Of Chlodowsky Operators Based On Q-Integer
(Ankara Univ, Fac Sci, 2016)In this paper, we introduce two different Kantorovich type generalization of the q-Chlodowsky operators. For the first operators we give some weighted approximation theorems and a Voronovskaja type theorem. Also, we present ... -
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 ... -
Some Characterizations Of Generalized Null Mannheim Curves In Semi-Euclidean Space
(INST BIOPHYSICS & BIOMEDICAL ENGINEERING, BULGARIAN ACAD SCIENCES, 2020)In the present paper, we investigate Cartan framed generalized null Mannheim curves in the four-dimensional semi-Euclidean space of index two. We construct the Cartan (or Frenet) frames and curvature functions of generalized ... -
Some characterizations of null osculating curves in the Minkowski space-time
(Estonian Academy Publishers, 2012)In this paper we give the necessary and sufficient conditions for null curves in E-1(4), to be osculating curves in terms of their curvature functions. In particular, we obtain some relations between null normal curves and ... -
Some characterizations of rectifying curves in the Euclidean space E4
(2008)In this paper, we define a rectifying curve in the Euclidean 4-space as a curve whose position vector always lies in orthogonal complement N{\perp} of its principal normal vector field N. In particular, we study the ... -
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 ... -
Some families of multivalently analytic functions with negative coefficients
(Academic Press Inc Jnl-Comp Subscriptions, 1997)The authors introduce and study three novel subclasses of analytic and p-valent functions with negative coefficients. In addition to finding a necessary and sufficient condition for a function to belong to each of these ... -
Some fixed point results for multivalued F-contractions on quasi metric spaces
(Springer-Verlag Italia Srl, 2017)In the present paper, taking into account recent conractive technique, which is called F-contraction, we provide some new fixed point results for multivalued mapping on some kind of complete quasi metric spaces. -
Some fixed point results on weak partial metric spaces
(Univ Nis, Fac Sci Math, 2013)The concept of partial metric p on a nonempty set X was introduced by Matthews [13] and it was slightly modified by Heckmann [11] as weak partial metric. In [12], the authors studied fixed point result of new extension of ... -
