Chengfei Xie, On the packing densities of superballs in high dimensions

Wednesday, June 22, 2022 @ 4:30 PM - 5:30 PM KST

Zoom ID: 870 0312 9412 (ibsecopro) [CLOSED]

Speaker

Chengfei Xie
Capital Normal University, Beijing

The sphere packing problem asks for the densest packing of nonoverlapping equal-sized balls in the space. This is an old and difficult problem in discrete geometry. In this talk, we give a new proof for the result that for 1<p<2, the translative packing density of superballs (a generalization of p balls) in Rn is Ω(n/2n).
This is joint work with Gennian Ge.
