On Ruled Surfaces with Pseudo Null Base Curve in Minkowski 3-Space
(Int Electronic Journal Geometry, 2016)
In this paper, we classify the ruled surfaces with a pseudo null base curve in Minkowski 3-space as spacelike, timelike and lightlike surfaces and obtain the corresponding striction curve and distribution parameter. In ...
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 ...
On Timelike Bertrand Curves In Minkowski 3-Space
(Honam Mathematical Soc, 2016)
In this paper, we study the timelike Bertrand curves in Minkowski 3-space. Since the principal normal vector of a timelike curve is spacelike, the Bertrand mate curve of this curve can be a timelike curve, a spacelike curve ...
(p, q)-Type Beta Functions Of Second Kind
(Tusi Mathematical Research Group, 2016)
In the present article, we propose the (p, q)-variant of beta function of second kind and establish a relation between the generalized beta and gamma functions using some identities of the post-quantum calculus. As an ...
The new forms of Voronovskaya's theorem in weighted spaces
(Springer, 2016)
The Voronovskaya theorem which is one of the most important pointwise convergence results in the theory of approximation by linear positive operators (l.p.o) is considered in quantitative form. Most of the results presented ...
New Types of Canal Surfaces in Minkowski 3-Space
(Springer Basel Ag, 2016)
Canal surface is a surface formed as the envelope of a family of spheres whose centers lie on a space curve. In Minkowski 3-space, many authors studied canal surfaces. However, when one investigates the papers, it is obvious ...
Fixed Point Results For α-Admissible Multivalued F -Contractions
(Univ Miskolc Inst Math, 2016)
In this study, we give some fixed point results for multivalued mappings using Pompeiu-Hausdorff distance on complete metric space. For this, we consider the alpha-admissibility of multivalued mappings. Our results are ...
A New Approach for the Approximations of Solutions to a Common Fixed Point Problem in Metric Fixed Point Theory
(Hindawi Publishing Corp, 2016)
We provide sufficient conditions for the existence of a unique common fixed point for a pair of mappings T,S : X > X where X is a nonempty set endowed with a certain metric. Moreover, a numerical algorithm is presented in ...
