具有$L_p$偏差最优阶的二维数字网

Digital nets in dimension two with the optimal order of $L_p$ discrepancy

Ralph Kritzinger, Friedrich Pillichshammer

摘要:

研究了二维数字网的有限$p$的$L_p$差异性。在2001年,Larcher和Pillichshammer确定了一类数字网,其Davenport意义下的对称化版本具有$\sqrt{\log N}/N$阶的$L_2$差异,由于Roth的著名结果,这是最可能的。然而,这种差异界限是否也适用于未经任何修改的原始数字网络,仍然是一个问题。在本文中,我们从上述类别中识别出不需要对称化的网络,以便为所有$p \in [1,\infty)$实现$L_p$差异的最佳顺序。我们的发现是在精神上的Bilyk从2013年,谁考虑了$L_2$差异的晶格组成的元素$(k/N,\{k α\})$为$k=0,1,\ldots,N-1$,并给出了丢番图性质的$α$保证最佳顺序的$L_2$差异。

英文摘要:

We study the $L_p$ discrepancy of two-dimensional digital nets for finite $p$. In the year 2001 Larcher and Pillichshammer identified a class of digital nets for which the symmetrized version in the sense of Davenport has $L_2$ discrepancy of the order $\sqrt{\log N}/N$, which is best possible due to the celebrated result of Roth. However, it remained open whether this discrepancy bound also holds for the original digital nets without any modification. In the present paper we identify nets from the above mentioned class for which the symmetrization is not necessary in order to achieve the optimal order of $L_p$ discrepancy for all $p \in [1,\infty)$. Our findings are in the spirit of a paper by Bilyk from 2013, who considered the $L_2$ discrepancy of lattices consisting of the elements $(k/N,\{k α\})$ for $k=0,1,\ldots,N-1$, and who gave Diophantine properties of $α$ which guarantee the optimal order of $L_2$ discrepancy.
