We propose here a new method for the investigation of embedding operators. It is based on an exact description of classes of homeomorphisms that induce change of variables operators on the Sobolev spaces. This method permits to obtain new exact results about embedding operators Wp1(G){right arrow, hooked}Lq(G) (or C(G)) in domains G ⊂ ℝn with irregular boundaries. For these types of domains the behavior of the limiting embedding exponent q1,G*(p) is very complicated and surprising. We construct classes of simply connected domains with nonsmooth function q1,G*(p) and a class of multiply connected domains with discontinuous function q1,G*(P).
