Covering numbers and "low $M^{*}$-estimate" for quasi-convex bodies
A. E. Litvak, V. D. Milman, and A. Pajor
This 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.
