In the present paper, we study pointwise approximation by Bernstein–Durrmeyer type
operators in the mobile interval x∈ 0, 1-1 n+ 1, with use of Peetre's K-functional and ω φ λ 2 …

We define the associated geometric series for a large class of positive linear operators and
study the convergence of the series in the case of sequences of admissible operators. We …

A first objective of our paper is to obtain a generalized version of Voronovskaya's theorem in
the form of the limit of ns (L n− I) sf, s∈ N, when L n are certain positive linear operators …

In this paper we investigate the power series of Beta operators. We first study the
convergence of this series and describe the Voronovskaya operator A and the inverse …

We study power series of members of a class of positive linear operators reproducing linear
