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. Gaussian random variables WebJun 13, 2024 · In 1947, M. S. Macphail constructed a series in $\\ell_{1}$ that converges unconditionally but does not converge absolutely. According to the literature, this result helped Dvoretzky and Rogers to finally answer a long standing problem of Banach Space Theory, by showing that in all infinite-dimensional Banach spaces, there exists an …

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.
