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 .

We derive the tight constant in the multivariate version of the Dvoretzky–Kiefer–Wolfowitz inequality. The inequality is leveraged to construct the first fully non-parametric test for multivariate probability distributions including a simple formula for the test statistic. We also generalize the test under appropriate.
