Soit R une variété riemannienne de volume fini, Δ l’opérateur laplacien sur R. Pour certains sous-espaces des algèbres de Wiener et Royden sur R, on construit une décomposition canonique liée à l’opérateur itéré ΔΔ. Si u est une solution de l’équation biharmonique ΔΔu=0, les valeurs de u et Δu à la frontière idéale déterminent les composantes de u suivant la décomposition.

Let R be a smooth Riemannian manifold of finite volume, Δ its Laplace (-Beltrami) operator. Canonical direct-sum decompositions of certain subspaces of the Wiener and Royden algebras of R are found, and for biharmonic functions (those for which ΔΔu=0) the decompositions are related to the values of the functions and their Laplacians on appropriate ideal boundaries.
