Equivalence of anchored and ANOVA spaces via interpolation
AI总结:
研究通过插值方法扩展了锚定空间与ANOVA空间在不同p范围内的等价性条件,适用于一阶混合导数有界于L_p的情况。
摘要:
我们考虑具有第一阶混合导数有界于L_p的函数的加权锚定和ANOVA空间。最近,Hefter、Ritter和Wasilkowski在p=1和p=∞的情况下建立了权重条件,确保相应范数在维度均匀或仅多项式依赖于维度时的等价性。我们扩展这些结果到整个p∈[1,∞]的范围。展示了如何通过插值实现这一点。
英文摘要:
We consider weighted anchored and ANOVA spaces of functions with first order mixed derivatives bounded in $L_p$. Recently, Hefter, Ritter and Wasilkowski established conditions on the weights in the cases $p=1$ and $p=\infty$ which ensure equivalence of the corresponding norms uniformly in the dimension or only polynomially dependent on the dimension. We extend these results to the whole range of $p\in [1,\infty]$. It is shown how this can be achieved via interpolation.
