Abstract:	Summary Integral representations of junctions in the anisotropic Sobolev spaces $mathop {W^{k,p} }limits^0 left( Omega right)$ on unbounded domains are used in the study of the embeddings of these spaces into Lebesgue spaces. Estimates of entropy numbers of the embedding $mathop {W^{k,p} }limits^0 left( Omega right) to L^Q left( Omega right)$ are obtained, where k, p and q satisfy certain conditions and where is a certain type of quasibounded domain,
