An Ill Posed Problem in SBV 0 2 (Ω)

Ana Cristina Barroso, José Matias

We study existence of solutions in

SBV_0^2(\Omega) S B V 0 2 ( Ω )
of a variational problem involving bulk and interfacial energy terms, but with the bulk energy not attaining a minimum at the prescribed boundary value. We obtain an expression for the relaxed energy and give some properties satisfied by the solutions of the relaxed problem.
