L'auteur rappelle la définition des espaces de Sobolev anisotropes avec poids \(L_{\omega,k}^ p(\mathbb{R}^ N)\) ainsi que celle des espaces de potentiel avec poids \({\mathcal L}_{\omega,\alpha}^ p(\mathbb{R}^ N)\) (cf. N. Miller). Il établit un théorème de trace sur \(\Omega=\{(x,\psi(x))\), \(x\in\mathbb{R}^{N-1}\}\), application linéaire continue de \[ {\mathcal L}_{\omega,\alpha}^ p(\mathbb{R}^ N) \qquad \text{dans} \qquad L_{\omega_ 1}^ p(\Omega) \qquad \text{ (Théorème 3.1)}. \] Il étend ce résultat au cas inhomogène selon les directions de \(\mathbb{R}^ N\) et pour \(\Omega=\mathbb{R}^{N-M}\).
