Abstract
A necessary condition called \(H_\mu ^{1,p}\)-quasiconvexity on p-coercive integrands is introduced for the lower semicontinuity with respect to the strong convergence of \(L^p_\mu (X;\mathbb {R}^m)\) of integral functionals defined on Cheeger–Sobolev spaces. Under polynomial growth conditions it turns out that this condition is necessary and sufficient.
