Soit Td=Rd/Zd le tore plat d-dimensionnel. Pour d=2 et d=3, on établit des bornes supérieures et inférieures uniformes sur les restrictions des fonctions propres de l'opérateur de Laplace–Beltrami à des surfaces lisses de courbure non nulle.

Let Td=Rd/Zd be the d-dimensional flat torus. We establish for d=2,3 uniform upper and lower bounds on the restrictions of the eigenfunctions of the Laplacian to smooth hyper-surfaces with non-vanishing curvature.
