Abstract: "A characterization of the surface energy density for the relaxation in BV([omega];R[superscript p]) of the functional u -> [integral subscript omega]f(x, u(x), [delta]u(x))dx is obtained. A 'slicing' technique is used allowing to patch together sequences without increasing their total energy."
