Abstract:

In this note, extension of the ideas used by Korovkin, Bojanic and Roulier, Karlin and Studden, Lorentz and Schumaker are studied in order to treat various aspects of approximation of continuous functions by operators which preserve generalized convexity in the sense of Karlin and Studden, and Ziegler.
