Let be a noncompact Riemannian manifold of dimension . Then there exists a proper embedding of into by harmonic functions on . It is easy to find 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.
Soit une variété riemannienne non compacte à dimensions. Alors il existe un plongement régulier et propre , de dans tel que les fonctions sont harmoniques sur . Il est facile de trouver 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.
