Nous étudions les approximations des fonctions de Green dans un domaine Ω obtenues par approximation de la masse de Dirac . Nous montrons que sous certaines conditions, ces approximations sont monotones, ce qui peut paraître surprenant.
We study the approximations of the Green's function in a domain Ω obtained from an approximation of the Dirac mass . We prove that under some conditions, these approximations converge monotonically to , a rather surprising result.
