Direct and converse results for q-Bernstein operators
Published online by Cambridge University Press: 28 May 2009
Abstract
Direct and converse theorems are established for the q-Bernstein polynomials introduced by G. M. Phillips. The direct approximation theorems are given for the second-order Ditzian–Totik modulus of smoothness. The converse results are theorems of Berens–Lorentz type.
