On a subclass of C1 functions for which the Lagrange interpolation yields the Jackson order of approximation

We continue the investigation initiated by Mastroianni and Szabados on question whether Jackson's order of approximation can be attained by Lagrange interpolation for a wide class of functions. Improving a recent result of Mastroianni and Szabados, we show that for a subclass of C1 functions th...
