Abstract:

We discuss here recent developments on the convergence of the q-Bernstein polynomials Bsub nf which replaces the classical Bernstein polynomial with a one parameter family of polynomials. In addition, the convergence of iterates and iterated Boolean sum of q-Bernstein polynomial will be considered. Moreover a q-difference operator Dsub qf defined by Dsub qf fX,QX is applied to q-Bernstein polynomials. This gives us some results which complement those concerning derivatives of Bernstein polynomials. It is shown that, with the parameter 0 is less than q is less than or equal to 1, if the change in k, fsub r is greater than or equal to 0 then Dksub qBsub nf is greater than or equal to 0. If f is monotonic so is Dsub qBsub nf. If f is convex then D2sub qBsub nf is greater than or equal to 0.
