Let X be a rearrangement‐invariant Banach function space on Q where Q is a cube in R n and letV 1 X ( Q )be the Sobolev space of real‐valued weakly differentiable functions f satisfying | ∇ f | ∈ X ( Q ) . We establish a reduction theorem for an embedding of the Sobolev spaceV 1 X ( Q )into spaces of Campanato, Morrey and Hölder type. As a result we obtain a new characterization of such embeddings in terms of boundedness of a certain one‐dimensional integral operator on representation spaces.
