## Approximation operators constructed by means of Sheffer sequences

Abstract In this paper we introduce a class of positive linear operators by using the “umbral calculus”, and we study…

## On approximation by some Bernstein–Kantorovich exponential-type polynomials

AbstractSince the introduction of Bernstein operators, many authors defined and/or studied Bernstein type operators and their generalizations, among them are…

## The iterates of positive linear operators with the set of constant functions as the fixed point set

AbstractLet Omega subset of R-p, p is an element of N* be a nonempty subset and B(Omega) be the Banach…
