Nous considérons l’opérateur de Dirac en dimension dont la masse est supposée grande à l’extérieur d’un ouvert borné et régulier . Nous démontrons que son spectre approche celui de l’opérateur de Dirac sur qui intègre dans son domaine les conditions au bord dites « MIT bag ». L’analyse asymptotique est réalisée grâce à l’usage de coordonnées tubulaires et à l’analyse d’un problème d’optimisation unidimensionnel dans la direction normale.
The Dirac operator, acting in three dimensions, is considered. Assuming that a large mass lies outside a smooth enough and bounded open set , it is proved that its spectrum approximates the one of the Dirac operator on with the MIT bag boundary condition. The approximation, modulo an error of order , is carried out by introducing tubular coordinates in a neighborhood of and analyzing one dimensional optimization problems in the normal direction.
