Exponential improvements for superball packing upper bounds

Ashwin Sah, Mehtaab Sawhney, David Stoner +1

We prove that for all fixed $p>2$, the translative packing density of unit ${\ell }_p$-balls in ${\mathbb{R}}^n$ is at most $2^{({\gamma }_p+o(1))n}$ with ${\gamma }_p<-1/p$. This is the first e…
