We study the asymptotic behaviour of a sequence of strongly degenerate parabolic equations with , . The main problem is the lack of compactness, by-passed via a regularity result. As particular cases, we obtain -convergence for elliptic operators , -convergence for parabolic operators , singular perturbations of an elliptic operator and , possibly .
