摘要
通过用一元小波的张量积构造多元小波基,给出其双曲部分和对混合光滑Sobolev类逼近的 Jackson及 Bernstein 型不等式估计。
In this paper, the Jackson and Bernstein inequalities for the approximation of Sobolev classes with mixed smoothness by certain hyperbolic partial sums of multivariate wavelet bases formed by tensor products of univariate wavelets are obtained.
