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 ...
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 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 ...
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 ...
Kantorovich-type generalization of parametric Baskakov operators
(Wiley, 2019)
In this manuscript, we define a Kantorovich generalization of the nonnegative parametric Baskakov operators. After that, the weighted uniform convergence of the generalized operators is proved. Also, we present Voronovskaja-type ...
Two fixed point results for multivalued F-contractions on M-metric spaces
(Springer-Verlag Italia Srl, 2019)
In this article, by considering Feng-Liu's technique, we present new fixed point results for multivalued mappings which are regarding to F-contraction on M-complete M-metric space. Then, we provide some nontrivial examples ...
Power Series of Positive Linear Operators
(Springer Basel Ag, 2019)
We describe a unifying approach for studying the power series of the positive linear operators from a certain class. For the same operators, we give simpler proofs of some known ergodic theorems.
Some New Quaternionic Quadratics with Zeros in Terms of Second Order Quaternion Recurrences
(Springer Basel Ag, 2019)
In this paper a comprehensive analysis of the Horadam quaternion zeros for some new types of bivariate quadratic quaternion polynomial equations is presented.
Suzuki Type Fixed Point Result for Rational theta-Contraction on Complete Metric Spaces
(Southeast Asian Mathematical Soc-Seams, 2019)
In this paper, we present a new approach to fixed point theorems for single valued contraction mappings defined on complete metric spaces. We introduce a new concept called Suzuki type rational theta*-contraction and prove ...
A New Method For Construction Of Ph-Helical Curves In E-3
(Publ House Bulgarian Acad Sci, 2019)
Helices curves are characterized by the property that their unit tangents maintain a constant inclination with respect to a fixed line, the axis of the helix. If a polynomial space curve is helical, it must be a ...
