We investigate a known problem whether a Sobolev homeomorphism between domains incan change sign of the Jacobian. The only case that remains open is when,. We prove that if, and a sense-preserving homeomorphismfsatisfies,and eitherfis Hölder continuous on almost all spheres of dimension [n/ 2], oris Hölder continuous on almost all spheres of dimensions, then the Jacobian offis non-negative,, almost everywhere. This result is a consequence of a more general result proved in the paper. Here [x] stands for the greatest integer less than or equal tox.
