WebTheorem 1.2 yields a very short proof (complete details in 3 pages) of the the nonlinear Dvoretzky theorem for all distortions D>2, with the best known bounds on the exponent (D). In a sense that is made precise in Section 1.2, the above value of (D) is optimal for our method. 1.1. Approximate distance oracles and limitations of Ramsey partitions.

WebJan 1, 2004 · Dvoretzky theorem Gaussian random variables Gaussian measures 2000 MSC 46B20 46B09 28C20 46G12 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. WebThe relation between Theorem 1.3 and Dvoretzky Theorem is clear. We show that for dimensions which may be much larger than k(K), the upper inclusion in Dvoretzky Theorem (3) holds with high probability. This reveals an intriguing point in Dvoretzky Theorem. Milman’s proof of Dvoretzky Theorem focuses on the left-most inclusion in (3).
