Abstract:

Given $\Omega$ subset of $*R*^n$, which is open, connected and bounded, with Lipschitz boundary and volume $
\Omega
$, we prove that a sequence $F_k$ of Dirichlet-type functionals defined on $H^1(\Omega;*R*^d)$, with volume constraints $*v*^k$ on $m$ fixed level-sets, and such that the sum of $v^k_i$ over $i=1..m$ is less than $
\Omega
$ for all $k$, gamma-converges, as $*v*^k$ tends to $*v*$ with $v_1+...+v_m =
\Omega
$, to the squared total variation on $BV(\Omega;*R*^d)$, with $*v*$ as volume constraint on the same level-sets.
