摘要：In the proving of Reshetnyak's theorems on stability of classes of conformal mappings the properties of mappings with bounded distortion play the important role. We consider the mappings which are analogues of mappings with bounded distortion. We construct these mappings as solutions of differential inequalities with null Lagrangians.
