Abstract

Our aim in this paper is to deal with Sobolev's embeddings for Sobolev–Orlicz functions with ∇uLp(·) logLq(·)(Ω) for Ω ⊂ n. Here p and q are variable exponents satisfying natural continuity conditions. Also the case when p attains the value 1 in some parts of the domain is included in the results.
