可求长d维流形的极小Riesz能量点集

Minimal Riesz Energy Point Configurations for Rectifiable d-Dimensional Manifolds

D. P. Hardin, E. B. Saff

摘要:

对于欧氏空间中的紧集A,我们考虑在A的所有N点子集上最小化Riesz s-能量(对应于势1/t^s)的最优(和近最优)N点配置的渐近行为,其中s>0。对于一类具有有限的正d维Hausdorff测度的流形A,我们证明了当s>d或s=d时,这种极小化构形的渐近极限分布(当N趋于无穷大且s固定时)等于d维Hausdorff测度.在后一种情况下,我们得到一个明确的公式中的最小能量的主导项。我们的结果是新的,即使是d维球的情况下。

英文摘要:

For a compact set A in Euclidean space we consider the asymptotic behavior of optimal (and near optimal) N-point configurations that minimize the Riesz s-energy (corresponding to the potential 1/t^s) over all N-point subsets of A, where s>0. For a large class of manifolds A having finite, positive d-dimensional Hausdorff measure, we show that such minimizing configurations have asymptotic limit distribution (as N tends to infinity with s fixed) equal to d-dimensional Hausdorff measure whenever s>d or s=d. In the latter case we obtain an explicit formula for the dominant term in the minimum energy. Our results are new even for the case of the d-dimensional sphere.
