Covering numbers and ``low $M^{*}$-estimate'' for quasi-convex bodies

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/153047This article gives estimates on covering numbers and diameters of random proportional sections and projections of symmetric quasi-convex bodies in $\mathbb R$. These results were known for the convex case and played an essential role in development of the theory. Because duality relations can not be applied in the quasi-convex setting, new ingredients were introduced that give new understanding for the convex case as well.Metric GeometryFunctional AnalysisCovering numbers and ``low $M^{*}$-estimate'' for quasi-convex bodiestext
