Approximation by (p, q)-Baskakov-Durrmeyer-Stancu Operators
(Springer Basel Ag, 2018)The present paper deals with the Stancu-type generalization of (p, q)-Baskakov-Durrmeyer operators. We investigate local approximation, weighted approximation properties of new operators and present the rate of convergence ... -
Bezier variant of the Bernstein-Durrmeyer type operators
(Springer Basel Ag, 2017)In the present paper, we introduce the Bezier-variant of Durrmeyer modification of the Bernstein operators based on a function , which is infinite times continuously differentiable and strictly increasing function on [0, ... -
Bi-null curves with constant curvatures in R-2(5)
(Springer Basel Ag, 2019)In the present paper, we classify bi-null curves with constant curvatures in semi-Euclidean 5-space R-2(5) with index 2. -
The Fibonacci Octonions
(Springer Basel Ag, 2015)In the present paper, we introduce the Fibonacci and Lucas octonions and give the generating function and Binet formulae for these octionions. In addition, we give some identities and properties of them. -
Fixed point theorems for Ćirić-type strong almost contractions on partial metric spaces
(Springer Basel Ag, 2012)In the present paper we prove some fixed point theorems for A dagger iriA double dagger-type strong almost contractions on partial metric spaces. We also give an illustrative example. -
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 ... -
k-Type bi-null slant helices in R-2(5)
(Springer Basel Ag, 2017)In the present paper, we give the notion of k-type bi-null slant helices in R-2(5), where k is an element of {0, 1, 2, 3, 4}. We give the necessary and sufficient conditions for bi-null curves to be k-type slant helices ... -
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 ... -
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 ... -
Nonlinear proximinal multivalued contractions on quasi-metric spaces
(Springer Basel Ag, 2017)In this paper, taking into account the concept of proximinal set, we obtain some new fixed point results for nonlinear proximinal multivalued contractions on some kind of complete quasi-metric spaces. Also, we present some ... -
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. -

(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 ... -
On differences of linear positive operators
(Springer Basel Ag, 2019)In this paper we consider two different general linear positive operators defined on unbounded interval and obtain estimates for the differences of these operators in quantitative form. Our estimates involve an appropriate ... -

(Springer Basel Ag, 2017)A modification of Szasz-Mirakyan operators is presented that reproduces the functions 1 and e(2ax), a > 0 fixed. We prove uniform convergence, order of approximation via a certain weighted modulus of continuity, and a ... -
On the Generalized Szasz-Mirakyan Operators
(Springer Basel Ag, 2014)In this paper, we construct sequences of Szasz-Mirakyan operators which are based on a function.. This function not only characterizes the operators but also characterizes the Korovkin set {1, rho, rho(2)} in a weighted ... -
Power Series of Positive Linear Operators
