Abstract

We consider a Bernstein–Schnabl operator \(L_n\) which commutes with the derivative and consequently can be represented as a differential operator with constant coefficients. The inverse of \(L_n\) restricted to polynomials is investigated. We obtain Voronovskaja type results for \(L_n^{-1}\) and compare them with the corresponding results for \(L_n\). A conjecture in this sense is presented.
