Abstract
We consider a sequence of Dirichlet problems for a nonlinear divergent operator A: Wm1(Ωs) → [Wm1(Ωs)]* in a sequence of perforated domains Ωs ⊂ Ω. Under a certain condition imposed on the local capacity of the set Ω \ Ωs, we prove the following principle of compensated compactness: \({\mathop {\lim }\limits_{s \to \infty }} \left\langle {Ar_s ,z_s } \right\rangle = 0\) , where rs(x) and zs(x) are sequences weakly convergent in Wm1(Ω) and such that rs(x) is an analog of a corrector for a homogenization problem and zs(x) is an arbitrary sequence from \({\mathop {W_m^1 }\limits^ \circ} (\Omega _s)\) whose weak limit is equal to zero.
