Yudin, V. A. Placement of points on a torus and in a plane. (English. Russian original) Zbl 1143.52303 Subbotin, Yu. N. (ed.), Function theory. Transl. from the Russian.

The author deals with the largest number of points on an \(n\)-dimensional torus with a given minimal pairwise distance. The problem is formulated as the densest packing of congruent balls on the torus. Estimates are given in the first part of the paper. For a special type of lattice spirals in the complex plane the packing radius is determined and the covering radius is estimated.For the entire collection see [Zbl 1116.42001]. Reviewer: Agota H.
