On the approximation of analytic functions by the \(q\)-Bernstein polynomials in the case \(q>1\)
Electronic transactions on numerical analysis, Tome 37 (2010), pp. 105-112
Since for q > 1, the q-Bernstein polynomials B are not positive linear operators on C[0, 1], the n,q investigation of their convergence properties turns out to be much more difficult than that in the case 0 q 1. In this paper, new results on the approximation of continuous functions by the q-Bernstein polynomials in the case q > 1 are presented. It is shown that if f $\in $C[0, 1] and admits an analytic continuation f (z) into z : |z| a, then B (f ; z) $\rightarrow f$ (z) as n $\rightarrow \infty $, uniformly on any compact set in z : |z| a.n,q
