Abstract.
A new method for the identification of the integral representation of a class of functionals defined on \(BV(\Omega ;{\Bbb R}^d)\times {\cal A}(\Omega)\)(where \({\cal A}(\Omega)\) represents the family of open subsets of Ω) is presented. Applications are derived, such as the integral representation of the relaxed energy in \(BV(\Omega;{\Bbb R}^d)\) corresponding to a functional defined in \(W^{1,1}(\Omega;{\Bbb R}^d)\) with a discontinuous integrand with linear growth; relaxation and homogenization results in \(SBV(\Omega;{\Bbb R}^d)\) are recovered in the case where bulk and surface energies are present.
