We give a compactness result with respect to G-convergence for sequences of mixed evolution (elliptic-parabolic) equations P h u = โ t (ฮผ h u)div(a h (x, t, Du)) = f , ฮผ h positive, null and negative. We show that the limit operator is of the form P u = โ t (ฮผu)div(a(x, t, Du)) and that ฮผ and a are
