改进的Hurwitz格的球填充下界

Improved sphere packing lower bounds from Hurwitz lattices

Stephanie Vance

摘要:

本文证明了在可除四维空间中球堆积密度的一个渐近下界。这个渐近下界改进了以前的渐近界的一个常数因子,并提高了不仅下界的球堆积密度,但也为晶格球堆积密度,事实上,赫尔维茨晶格球堆积密度。

英文摘要:

In this paper we prove an asymptotic lower bound for the sphere packing density in dimensions divisible by four. This asymptotic lower bound improves on previous asymptotic bounds by a constant factor and improves not just lower bounds for the sphere packing density, but also for the lattice sphere packing density and, in fact, the Hurwitz lattice sphere packing density.
