Dvoretzky's theorem
WebJan 1, 2004 · In this note we give a complete proof of the well known Dvoretzky theorem on the almost spherical (or rather ellipsoidal) sections of convex bodies. Our proof follows Pisier [18], [19]. It is accessible to graduate students. In the references we list papers containing other proofs of Dvoretzky’s theorem. 1.
