Constructive Approximation ( IF 2.7 ) Pub Date : 2021-04-08 , DOI: 10.1007/s00365-021-09534-5 Jordi Marzo , Albert Mas
We find upper bounds for the spherical cap discrepancy of the set of minimizers of the Riesz s-energy on the sphere \(\mathbb S^d.\) Our results are based on bounds for a Sobolev discrepancy introduced by Thomas Wolff in an unpublished manuscript where estimates for the spherical cap discrepancy of the logarithmic energy minimizers in \(\mathbb S^2\) were obtained. Our result improves previously known bounds for \(0\le s<2\) and \(s\ne 1\) in \(\mathbb S^2,\) where \(s=0\) is Wolff’s result, and for \(d-t_0<s<d\) with \(t_0\approx 2.5\) when \(d\ge 3\) and \(s\ne d-1.\)

最小里兹能量点的差异
我们找到球面上(\ mathbb S ^ d。\)的Riesz s-能量极小子集的球冠差异的上限。我们的结果基于托马斯·沃尔夫(Thomas Wolff)在未出版的Sobolev差异的界限在手稿中获得了对数能量极小值在\(\ mathbb S ^ 2 \)中的球形盖差异的估计值。我们的结果改善了\(\ mathbb S ^ 2,\)中\(0 \ le s <2 \)和\(s \ ne 1 \)的已知边界,其中\(s = 0 \)是Wolff的结果,并且为\(d-T_0 <S <d \)与\(T_0 \约2.5 \)时\(d \ GE 3 \)和\(s \ ne d-1。\)
