摘要

Hadwiger’s conjecture in combinatorial geometry states that any n-dimensional convex body can be covered by at most \(2^n\) 2 n smaller bodies homothetic to the original body. We prove Hadwiger’s conjecture for strongly monotypic polytopes by studying a characterization of the set of normals. One of the nice properties of (strongly) monotypic polytopes is that the set of normals decides the combinatorics of the polytope.
