摘要
Sobolev空间的Cardinal样条逼近已有较多研究.在此研究了Sobolev空间的Cardinal-Hermite插值问题,构造了插值逼近算子,并利用插值算子对多项式的重构性质获得了逼近阶的估计.
The cardinal spline approximation of Sobolev spaces is studied in many papers by the authors. Here the approximation of Cardinal-Herrnite intepolation is considered and the approximation operator is constructed and the approximation order is obtained by using the property of reproducing polynomials of the operator.
