Abstract

It is studied the lower semicontinuity of functionals of the type \int_{\Omega} f(x, u, v,\nabla u)dx with respect to the (W^{1,1} \times L^p)-weak*topology. Moreover in absence of lower semicontinuity, it is also provided an integral representation in W^{1,1}\times L^p for the lower semicontinuous envelope.
