An isoperimetric problem for three-dimensional parallelohedra

Metric Geometry 2022-03-09 v4

Abstract

The aim of this note is to investigate isoperimetric-type problems for 33-dimensional parallelohedra; that is, for convex polyhedra whose translates tile the 33-dimensional Euclidean space. Our main result states that among 33-dimensional parallelohedra with unit volume the one with minimal mean width is the regular truncated octahedron.
