Approximation properties of recursively defined Bernstein-type operators

M Campiti, G Metafune - journal of approximation theory, 1996 - Elsevier
We consider a generalization of classical Bernstein operators obtained by replacing the
binomial coefficients with general ones satisfying a suitable recursive relation. We study the …

Lototsky-Schnabl operators on compact convex sets and their associated limit semigroups
