The starting point of this note is Milman’s version of Dvoretzky’s Theorem [ 11 – 13 ]—which deals with random sections/projections of a convex, centrally symmetric set in \mathbb {R}^n with a nonempty interior (a convex body). The question is to identify the dimension k for which a ‘typical’ linear image of ...
