We propose a domain embedding (fictitious domain) method for elliptic equations subject to mixed boundary conditions, and prove the sharp convergence rate. The theory provides a unified treatment for Dirichlet, Neumann, and Robin boundary conditions.
Nous proposons une méthode de domaine fictif dans la résolution de problèmes elliptiques avec conditions aux limites mixtes. Nous établissons une estimation précise du taux de convergence de la solution d'un problème approché. La théorie donne un traitement unifié dans les cas de conditions aux limites de Dirichlet, de Neumann et de Robin.
