Abstract:Given a bounded regular domain with cylindrical symmetry, functions having such symmetry and belonging to W 1,p can be embedded compactly into some weighted L q spaces, with q superior to the critical Sobolev exponent. A similar result is also obtained for variable exponent Sobolev space W 1,p(x). Furthermore, we give a simple application to the p(x)-Laplacian problem.
