Almost Picard Operators
(Amer Inst Physics, 2019)The concept of Picard operator is one of the most important concept of fixed point theory. As known, a self mapping T of a metric space X is called Picard operator (PO) if it has unique fixed point and every Picard iteration ... -
An application of Ritt-Wu's zero decomposition algorithm to null Bertrand type curves in Minkowski 3-space
(Hacettepe Univ, Fac Sci, 2010)Bertrand curves were first studied using a computer by W. -T. Wu in (A mechanization method of geometry and its applications II. Curve pairs of Bertrand type, Kexue Tongbao 32, 585-588, 1987). The same problem was studied ... -
Applications of (p,q)-gamma function to Szász Durrmeyer operators
(Publications L Institut Mathematique Matematicki, 2017)We define a (p, q) analogue of Gamma function. As an application, we propose (p, q)-Szasz-Durrmeyer operators, estimate moments and establish some direct results. -

(De Gruyter Poland Sp Zoo, 2017)We deal with the approximation properties of a new class of positive linear Durrmeyer type operators which offer a reconstruction of integral type operators including well known Durrmeyer operators. This reconstruction ... -
Bernstein-Type Operators That Reproduce Exponential Functions
(Element, 2018)In this paper we recover a generalization of the classical Bernstein operators introduced by Morigi and Neamtu in 2000. Specifically, we focus on a sequence of operators that reproduce the exponential functions exp(mu t) ... -
Bleimann, Butzer, and Hahn Operators Based on the q-Integers
(Hindawi Publishing Corporation, 2007)We give a new generalization of Bleimann, Butzer, and Hahn operators, which includes q-integers. We investigate uniform approximation of these new operators on some subspace of bounded and continuous functions. In Section ... -
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 ... -
