| Abstract: | Summary We investigate the approximation behavior of the so-called Jackson interpolation operator. We will also study the K-functional deduced from this operator. As a result we obtain the asymptotic expression of this K-functional. |
| Keywords: | degree of approximation Jackson interpolation operator asymptotic expression K-functional |
