Inverse result in simultaneous approximation by Baskakov-Durrmeyer-Stancu operators

On Simultaneous Approximation of Modified Baskakov-Durrmeyer Operators

“…γ = 1, the operators (1.1) reduce to the operators very recently studied in [1,2]. Inverse results of same type of operators were establish in [3]. Also, if α = β = 0 , the operators (1.1) reduce to the operators recently studied in [4] and if α = β = 0 and γ = 1, the operators (1.1) reduce to the operators studied in [5].…”

“…The q-analog of the operators (1.1) is discussed in [6]. We refer to some of the important papers on the recent development on similar type of the operators [7,8,9]. The present paper deals with the study of simultaneous approximation for the operators B α,β n,γ .…”

Approximation properties of Chlodowsky variant of ( p , q ) $(p,q)$ Bernstein-Stancu-Schurer operators

“…Besides this, we also refer to some recent related work on this topic: e.g. ( [12], [13], [14], [15], [17]). Now, we recall certain notations of (p, q)-calculus.…”

On Generalized Szász-Mirakyan operators

“…Durrmeyer type generalization of Jain operators and its approximation properties was elaborated by Tarabie [13], Mishra and Patel [14], Patel and Mishra [15] and Agratini [16]. See some related work in this area [17][18][19]. Motivated by this we give further modification of Jain operators in this paper with the help of a generalized Poisson type distribution, consider its convergence properties and give its degree of approximation, asymptotic formula, the statistical convergence.…”
