Lower semicontinuity results with respect to weak-formula28 convergence in the sense of measures and with respect to weak convergence in formula30 are obtained for functionals
where admissible sequences formula32 satisfy a first order system of PDEs formula34. We suppose that formula36 has constant rank, f is formula36-quasiconvex and satisfies the non standard growth conditions
with formula42 for formula44, formula46 for p>N-1. In particular, our results generalize earlier work where formula50 reduced to formula52 for some formula54.
