Voronovskaya type results for Bernstein-Chlodovsky operators preserving $e^{2x}$

In this paper we continue the study of certain Bernstein-Chlodovsky operators B_n^∗ preserving the exponential function e^{2x} (x ≥0), recently introduced in [4]. In particular, we prove some Voronovskaya type theorems and we deduce some properties of the B_n^∗’s, such as saturation results. We also compare this new class of operators with the classical Bernstein-Chlodovsky ones, proving that the operators B_^∗ provide better approximation results for certain functions.
