General helices with spacelike slope axis in Minkowski 3-space
(World Scientific Publ Co Pte Ltd, 2019)In the present paper, we consider general helix with spacelike slope axis for all possible types of curves in Minkowski 3-space. We give the conditions under which the curves in Minkowski 3-space have spacelike slope axis. ... -
Quaternions: Quantum calculus approach with applications
(Academic Publication Council, 2019)In this paper we introduce two types of quaternion sequences with components including quantum integers. We also introduce quantum quaternion polynomials. Moreover, we give some properties and identities for these quantum ... -
Common Fixed Point Results for Generalized Wardowski Type Contractive Multi-Valued Mappings
(Mdpi, 2019)In this paper, we introduce generalized Wardowski type quasi-contractions called alpha-(phi,Omega)-contractions for a pair of multi-valued mappings and prove the existence of the common fixed point for such mappings. An ... -
Quantitative estimates for bivariate Stancu operators
(Wiley, 2019)In this paper, we introduce Voronovskaja-type and Gruss-Voronovskaja- type theorems in quantitative mean with the help of the usual modulus of continuity for bivariate Stancu operators, which are different from a tensor ... -
On pointwise convergence of the family of Urysohn-type integral operators
(Wiley, 2019)In this paper, we consider a family of nonlinear integral operators of Urysohn-type and study the pointwise convergence of the family at characteristic points of L-1-function. The kernel K-lambda(x, t, u(t)) depends on the ... -
Approximation properties of Szasz-Mirakyan-Kantorovich type operators
(Wiley, 2019)In this paper, we introduce and study new type Szasz-Mirakyan-Kantorovich operators using a technique different from classical one. This allow to analyze the mentioned operators in terms of exponential test functions instead ... -
Structure equations and constraint manifolds on Lorentz plane
(Wiley, 2019)Calculating the structure equation of a chain is important to represent the position of the end link on the chain. Furthermore, the structure equation helps to determine the constraint manifold of the chain. The constraint ... -
On Darboux helices in Euclidean 4-space
(Wiley, 2019)The notion of Darboux helix in Euclidean 3-space was introduced and studied by Yayli et al. 2012. They show that the class of Darboux helices coincide with the class of slant helices. In a special case, if the curvature ... -
Reconstruction of Baskakov operators preserving some exponential functions
(Wiley, 2019)The present paper deals with a new modification of Baskakov operators in which the functions exp(mu t) and exp(2 mu t), mu > 0 are preserved. Approximation properties of the operators are captured, ie, uniform convergence ... -
On approximation by some Bernstein-Kantorovich exponential-type polynomials
(Springer, 2019)Since the introduction of Bernstein operators, many authors defined and/or studied Bernstein type operators and their generalizations, among them are Morigi and Neamtu (Adv Comput Math 12:133-149, 2000). They proposed an ... -
Pointwise multipliers between weighted copson and cesàro function spaces
(Walter De Gruyter Gmbh, 2019)In this paper the solution of the pointwise multiplier problem between weighted Copson function spaces Cop(p1), (q1) ((u1,) (v1)) and weighted Cesaro function spaces Ces(p2, q2) (u(2), v(2)) is presented, where p(1), p(2), ... -

(Springer Basel Ag, 2018)In the present paper, we construct and investigate a variant of modified (p, q)-Szasz-Mirakyan operators, studied in Acar (Math Methods Appl Sci 39(10):2685-2695, 2016), which reproduce the test function The order of ... -
Note on Szasz-Mirakyan-Durrmeyer Operators Preserving e(2ax), a > 0
(Taylor & Francis Inc, 2018)In the current article, we study Szasz-Mirakyan-Durrmeyer operators which reproduces constant and e(2ax), a > 0 functions. We discuss a uniform estimate and estimate a quantitative asymptotic formula for the modified operators. -
Generalized Lupas Operators
(Amer Inst Physics, 2018)In this work, by taking a continuously differentiable, increasing and unbounded function rho, we consider an extension of the Lupas operator L-n in the form L-n (f o rho(-1)) o rho for convenient functions f on [0, infinity). ... -
New Results for General Helix in Euclidean 3-space
(Amer Inst Physics, 2018)Finding parametric equation of a space curve is not easy task when its curvature functions are given. It is well known that this problem is known as fundamental theorem of a space curve. If the curvature functions are ... -
Rodrigues parameters on dual hyperbolic unit sphere H20
(Taylor & Francis Ltd, 2018)Rodrigues parameters depend on the tangent of the half rotation angle in Euclidean space but in Dual space, dual Rodrigues parameters contain both rotation angle and distance corresponding the shortest distance between the ... -
