Bernstein durrmeyer operators based on two parameters
(Univ Nis, 2016)In the present paper, we study the applications of the extension of quantum calculus based on two parameters. We define beta function and establish an identity with gamma function, for two parameters (p, q), ie. the ... -

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 ... -
Fixed points of ordered F-contractions
(Hacettepe Univ, Fac Sci, 2016)In his recent paper, Wardowski [16] introduced the concept of F-contraction, which is a proper generalization of ordinary contraction on a complete metric space. Then, some generalizations of F-contractions including ... -
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 ... -
Approximation by modified Szasz-Durrmeyer operators
(Springer, 2016)The main goal of this paper is to introduce Durrmeyer modifications for the generalized Szasz-Mirakyan operators defined in (Aral et al., in Results Math 65:441-452, 2014). The construction of the new operators is based ... -
A new approach to the Assad-Kirk fixed point theorem
(Springer Basel Ag, 2016)In the present paper, considering the Wardowski's technique, we give a new approach to the Assad-Kirk fixed point theorem on metrically convex metric spaces. We also provide a nontrivial example showing that our result is ... -
On Kantorovich modification of (p, q)-Baskakov operators
(Springeropen, 2016)The concern of this paper is to introduce a Kantorovich modification of (p, q)-Baskakov operators and investigate their approximation behaviors. We first define a new (p, q)-integral and construct the operators. The rate ... -
A note on bi-periodic Fibonacci and Lucas quaternions
(Pergamon-Elsevier Science Ltd, 2016)Motivated by the our recent work in Tan et al., 2016, related to the bi-periodic Fibonacci quaternions, here we introduce the bi-periodic Lucas quaternions that gives the Lucas quaternions as a special case. We give the ... -
On Generalized Spacelike Mannheim Curves in Minkowski Space-Time
(Natl Acad Sciences India, 2016)In this paper, by taking consideration of all possible causal characters of the plane spanned by {B-1*; B-2* }, we give the necessary and sufficient conditions for spacelike curves in E-1(4) to be generalized spacelike ... -
General Helices with Timelike Slope Axis in Minkowski 3-Space
(Springer Basel Ag, 2016)In the present paper, we consider the general helices in Minkowski 3-space to have a constant timelike slope axis. As a result, we show that there exists no pseudo null helix with constant timelike slope axis or spacelike ... -
q-Voronovskaya type theorems for q-Baskakov operators
(Wiley, 2016)In the present paper, we prove quantitative q-Voronovskaya type theorems for q-Baskakov operators in terms of weighted modulus of continuity. We also present a new form of Voronovskaya theorem, that is, q-Gruss-Voronovskaya ... -
A Note on Boundedness of the Hardy-Littlewood Maximal Operator on Morrey Spaces
(Springer Basel Ag, 2016)In this paper we prove that the Hardy-Littlewood maximal operator is bounded on Morrey spaces M-1,M-lambda(R-n), 0 <= lambda < n for radial, non-increasing functions on R-n. -
Lyapunov-type inequalities for a fractional p-Laplacian equation
(Springeropen, 2016)In this paper, we present new Lyapunov-type inequalities for a fractional boundary value problem that models a turbulent flow in a porous medium. The obtained inequalities are used to obtain a lower bound for the eigenvalues ... -
(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 ... -
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 ... -
Approximation by k-th order modifications of Szász-Mirakyan operators
(Akademiai Kiado Rt, 2016)In this paper, we study the k-th order Kantorovich type modication of Szasz-Mirakyan operators. We first establish explicit formulas giving the images of monomials and the moments up to order six. Using this modification, ... -
