| 5 | UNCONSTRAINED AND CONVEX POLYNOMIAL APPROXIMATION IN C[-1,1]显示文摘Some estimates for unconstrained and convex polynomial approximation in the uniform metric are obtained. These results are given in terms of the Ditzian-Totik moduli of smoothness≤1 with ψ(x)= 1-x2. The construction of the approximating polynomials does not depend on AAA. | K. A.
