We prove that the optimal error of recovery in the norm of functions from a class can be bounded above by the value of the Kolmogorov width of in the uniform norm. We demonstrate on a number of examples of from classes of functions with mixed smoothness that the obtained inequality provides a powerful tool for estimating errors of optimal recovery.

我们证明了在 一类功能的规范 可以被上面的Kolmogorov宽度值限制 在统一规范中。我们通过以下示例进行演示 从具有混合平滑度的函数类别可以看出,获得的不等式为估算最佳回收率的误差提供了有力的工具。
