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), ... -
On a Modification of (p, q)-Szasz-Mirakyan Operators
(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. -
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 ... -

(Univ Nis, Fac Sci Math, 2018)In this paper, we investigate general helices with lightlike slope axis. We give necessary and sufficient conditions for a general helix to have a lightlike slope axis. We obtain parametric equation of all general helices ... -
Blending Type Approximation By Bezier-Summation-Integral Type Operators
(Ankara Univ, Fac Sci, 2018)In this note we construct the Bezier variant of summation integral type operators based on a non-negative real parameter. We present a direct approximation theorem by means of the first order modulus of smoothness and the ... -

P-Contractive Mappings On Metric Spaces
(Mathematical Research Press-Math Res, 2018)In the present paper, we introduce a new concept of P-contractive mappings on metric spaces. We prove that every ordinary contractive mapping is also P-contractive but the converse may not be true in general. We provide ...
