Intuitive explanation of Dvoretzky
In mathematics, Dvoretzky's theorem is an important structural theorem about normed vector spaces proved by Aryeh Dvoretzky in the early 1960s, answering a question of Alexander Grothendieck. In essence, it says that every sufficiently high-dimensional normed vector space will have low-dimensional … See more For every natural number k ∈ N and every ε > 0 there exists a natural number N(k, ε) ∈ N such that if (X, ‖·‖) is any normed space of dimension N(k, ε), there exists a subspace E ⊂ X of dimension k and a positive definite See more • Vershynin, Roman (2024).

See more In 1971, Vitali Milman gave a new proof of Dvoretzky's theorem, making use of the concentration of measure on the sphere to show that a random k-dimensional subspace satisfies the above inequality with probability very close to 1.

A Measure-Theoretic Dvoretzky Theorem and …
WebJun 25, 2015 · 1 Introduction. 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 ...

Then there is a c > 0 depending on , L, L0 such that for " = 2 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). fish tbc
