A remark on the isotropy constant of polytopes

Alonso-Gutiérrez, D.

Resumen: It is known that the isotropy constant of any symmetric polytope with vertices is bounded by . We give a different proof of this result, which shows that the same estimate is true when the polytope is non-symmetric with vertices. We also make a remark on how an estimate of the isotropy constant of a symmetric polytope with facets of the order of , which can be easily deduced from known results, is also true for non-symmetric polytopes with facets.
