Local minimality of the volume-product at the simplex

Jaegil Kim, Shlomo Reisner

Research output: Contribution to journalArticlepeer-review


It is proved that the simplex is a strict local minimum for the volume product, P(K)=min z∈int(K)|K||Kz|, in the Banach-Mazur space of n-dimensional (classes of) convex bodies. Linear local stability in the neighborhood of the simplex is proved as well. The proof consists of an extension to the non-symmetric setting of methods that were recently introduced by Nazarov, Petrov, Ryabogin and Zvavitch, as well as proving results of independent interest concerning stability of square order of volumes of polars of non-symmetric convex bodies.
