Abstract

We consider the problem of minimizing the energy E ( u ) : = ∫ Ω | ∇ u ( x ) | 2 d x + ∫ S u ∩ Ω 1 + | [ u ] ( x ) | d H N - 1 ( x ) among all functions u ∈ SBV²(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(.) is proved and the asymptotic behaviour of the solutions is investigated.
