We prove some existence and regularity results for minimizers of a class of integralfunctionals, defined on vector-valued Sobolev functions u for which the volumes ofcertain level-sets {u = li} are prescribed, with i = 1, . . . ,m. More specifically, in thecase of the energy density W(x, u,Du) = |Du|2+F(u), we prove that minimizers existand are locally Lipschitz, if the function F and {l1, . . . , lm} verify suitable hypotheses.

Abstract
We prove some existence and regularity results for minimizers of a class of integralfunctionals, defined on vector-valued Sobolev functions u for which the volumes ofcertain level-sets {u = li} are prescribed, with i = 1, . . . ,m. More specifically, in thecase of the energy density W(x, u,Du) = |Du|2+F(u), we prove that minimizers existand are locally Lipschitz, if the function F and {l1, . . . , lm} verify suitable hypotheses.
