Soit M une variété riemannienne non compacte à n dimensions. Alors il existe un plongement régulier et propre f=(f 1 ,...,f 2n+1 ), de M dans R 2n+1 tel que les fonctions f 1 ,...,f 2n+1 sont harmoniques sur M. Il est facile de trouver 2n+1 fonctions harmoniques qui donnent un plongement régulier. Pour obtenir une telle application qui est à la fois propre, c’est plus subtil. On utilise les théorèmes de Lax-Malgrange et Aronszajn-Cordes dans la théorie d’équations elliptiques.

Let M be a noncompact Riemannian manifold of dimension n. Then there exists a proper embedding of M into R 2n+1 by harmonic functions on M. It is easy to find 2n+1 harmonic functions which give an embedding. However, it is more difficult to achieve properness. The proof depends on the theorems of Lax-Malgrange and Aronszajn-Cordes in the theory of elliptic equations.
