我们证明了当p> 2时,Rn中单位球的平移堆积密度至多为2(γ p+ o(1))n,其中γ p<− 1/p.这是自货车der Corput和Schaake(1936)以来高维空间的第一个指数改进.
We prove that for all fixed p> 2, the translative packing density of unit ℓ p-balls in R n is at most 2 (γ p+ o (1)) n with γ p<− 1/p. This is the first exponential improvement in high dimensions since van der Corput and Schaake (1936).
