Abstract

We study an eigenvalue problem concerning the vibration of an interface separating two non miscible fluids with different densities. We obtain an abstract theorem of existence generalizing a result due to J. Boujot [4]. We propose a method of approximation by penalization and we give an estimation of the error.
