Résumé

We consider the problem of minimizing the energy

E (u) : = \int_{Ω} {| \nabla u (x) |}^{2} d x + \int_{S_{u} \cap Ω} (1 + | [u] (x) |) d H^{N - 1} (x)

among all functions

u \in S B V^{2} (Ω)

for which two level sets

{u = l_{i}}

have prescribed Lebesgue measure

α_{i}

. Subject to this volume constraint the existence of minimizers for

E (\cdot)

is proved and the asymptotic behaviour of the solutions is investigated.
