Abstract:

Given $N$ points on a unit sphere in Euclidean $m$ space, $m \geqq 2$, we show that the sum of all distances which they determine plus their discrepancy is a constant. As applications we obtain (i) an upper bound for the sum of the distances which for $m \geqq 5$ is smaller than any previously known and (ii) the existence of $N$ point distributions with small discrepancy. We make use of W. M. Schmidt’s work on the discrepancy of spherical caps.
