Nous étudions un problème inverse de diffusion pour l’opérateur de Schrödinger discret sur un réseau carré , , avec un potentiel à support compact. Nous montrons que le potentiel est uniquement determiné en utilisant la matrice de diffusion à énergie fixée.
We study an inverse scattering problem for the discrete Schrödinger operator on the square lattice , , with compactly supported potential. We show that the potential is uniquely reconstructed from a scattering matrix for a fixed energy.
Keywords: Schrödinger operator, Scattering theory, Inverse Problem
Mot clés : l’opérateur de Schrödinger, la théorie de diffusion, le problème inverse
