$A$-Quasiconvexity

Abstract: This talk is about lower semicontinuity results for functionals of the type $v \to \int_{\Omega} f(x,v) \,dx$, under appropriate growth and continuity conditions on $f$, along weakly convergent sequences in $L^p$ that are constrained by a linear 1st order system of PDEs with smooth coefficients and constant rank.
