Nash isometric embedding theorem

Every compact $n$ -dimensional Riemannian manifold $M$ of class $C^{k}$ ( $3\leq k\leq\infty$ ) can be $C^{k}$ -isometrically imbedded in any small portion of a Euclidean space $\mathbb{R}^{N}$ , where

$N=\frac{1}{2}n(3n+11).$

Every non-compact $n$ -dimensional Riemannian manifold $M$ of class $C^{k}$ ( $3\leq k\leq\infty$ ) can be $C^{k}$ -isometrically imbedded in any small portion of a Euclidean space $\mathbb{R}^{N}$ , where

$N=(n+1)\frac{1}{2}n(3n+11).$

The original proof due to Nash relying on an iteration scheme has been considerably simplified. For an overview, see [2].
