摘要

基于宗庆后关于三维凸体平移堆积密度的研究[26]，我们提出了一种局部方法来估计八面体最密平移覆盖的密度θt (C 3)。因此，我们证明了 θt (C 3) ≥ 1 + 6.6 × 10-8，这是该密度的第一个非难下限。

Lower bound on the translative covering density of octahedra

Based on Zong’s work [26] on translative packing densities of 3-dimensional convex bodies, we present a local method to estimate the density θt (C 3) of the densest translative covering of an octahedron. As a consequence we prove that θt (C 3) ≥ 1 + 6.6 × 10–8, which is the first non-trivial lower bound for this density.

期刊介绍： Advances in Geometry is a mathematical journal for the publication of original research articles of excellent quality in the area of geometry. Geometry is a field of long standing-tradition and eminent importance. The study of space and spatial patterns is a major mathematical activity; geometric ideas and geometric language permeate all of mathematics.
