On Tensor Product Surfaces of Lorentzian Planar Curves with Pointwise 1-Type Gauss Map
(Int Electronic Journal Geometry, 2016)In this article, we study the tensor product surfaces of two Lorentzian planar,non-null curves to have pointwise 1-type Gauss map. -
Reinvestigation of bromination of 8-substituted quinolines and synthesis of novel phthalonitriles
(Acg Publications, 2016)Bromination of a series of 8-substituted quinolines was reinvestigated and specified for optimum yields and isolation conditions. Mono bromination of 8-hydroxyquinoline (2a) and 8-aminoquinoline (2c) gave mixture of mono ... -
Fixed-Point Theorems for Integral-Type Contractions on Partial Metric Spaces
(Springer, 2016)We present some fixed-point results for single-valued mappings on partial metric spaces satisfying a contractive condition of integral type. -
Quantitative Voronovskaya-Type Results for Polynomially Bounded Functions
(Springer Basel Ag, 2016)We prove quantitative Voronovskaya-type results and Gruss-Voronovskaya inequalities for polynomially bounded functions. The results are given in terms of suitable K-functionals and applied to linking Szasz-Mirakyan and ... -
Quantitative q-Voronovskaya and q-Gruss-Voronovskaya-type results for q-Szasz operators
(Walter De Gruyter Gmbh, 2016)In the present paper, we mainly study quantitative Voronovskaya-type theorems for q-Szasz operators defined in [19]. We consider weighted spaces of functions and the corresponding weighted modulus of continuity. We obtain ... -
On bi-null Cartan curves in semi-Euclidean 6-space with index 3
(Springer Basel Ag, 2016)In this paper, we study bi-null curves in semi-Euclidean 6-space with index 3, R-3(6). We construct the Frenet frame and Cartan curvature functions of bi-null curves in R-3(6). Also we discuss some properties of bi-null ... -
Generalized pseudo null Bertrand curves in semi-Euclidean 4-space with index 2
(Springer-Verlag Italia Srl, 2016)In this paper, we study generalized pseudo null Bertrand curves in semi-Euclidean 4-space E-2(4) with index 2. We get the necessary and sufficient conditions for pseudo null curves to be generalized Bertrand curves and we ... -
Approximation by generalized Baskakov-Durrmeyer-Stancu type operators
(Springer-Verlag Italia Srl, 2016)In this paper, we introduce Stancu type modification of generalized Baskakov-Durrmeyer operators and study their approximation properties. First, we derive the recurrence relation and central moments of these operators and ... -
On (1, 3)-Cartan null Bertrand curves in semi-Euclidean 4-space with index 2
(Springer Basel Ag, 2016)In this paper, we study generalized Cartan null Bertrand curves in semi-Euclidean 4-space E-2(4) with index 2. -
On discrete Picard operators
(Wiley-Blackwell, 2016)The present paper is concerned with the approximation properties of discrete version of Picard operators. We first give exact equalities for the moments of the operators. In calculations of these moments, Eulerian numbers ... -
Generalized Binomial Convolution of the mth Powers of the Consecutive Integers with the General Fibonacci Sequence
(De Gruyter Open Ltd, 2016)In this paper, we consider Gauthier's generalized convolution and then define its binomial analogue as well as alternating binomial analogue. We formulate these convolutions and give some applications of them. -
Elastic Sturmian spirals in the Lorentz-Minkowski plane
(De Gruyter Poland Sp Zoo, 2016)In this paper we consider some elastic spacelike and timelike curves in the Lorentz-Minkowski plane and obtain the respective vectorial equations of their position vectors in explicit analytical form. We study in more ... -
