Dvoretzky's theorem
WebNonlinear Dvoretzky Theory. The classical Dvoretzky theorem asserts that for every integer k>1 and every target distortion D>1 there exists an integer n=n (k,D) such that any. n-dimensional normed space contains a subspace of dimension k that embeds into Hilbert space with distortion D . Variants of this phenomenon for general metric spaces ... 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 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 … See more • Vershynin, Roman (2024).

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).
