AI总结:

本文通过构造性证明,展示非退化盒样条为分段多项式,并提出明确的内部区域多项式构造方法。

摘要:

对于非退化盒样条类,我们证明这些盒样条是分段多项式。这并非新结果,事实上是盒样条已知且有用的性质。然而,我们的证明是构造性的,本文的主要结果是由此证明推导出的结论,即提供任何非退化盒样条内部区域多项式片段的显式构造方案。

英文摘要:

For the class of non-degenerate box splines, we prove that these box splines are piecewise polynomial. This is not a new result, it is in fact a well known and useful property of box splines. However, our proof is constructive, and the main result of this work is a corollary that follows from this proof, namely one that gives an explicit construction scheme for the polynomial pieces in the interior regions of any non-degenerate box spline.
