On boundary Hölder continuity of Sobolev and Orlicz-Sobolev classes

Abstract: We study problems about estimates of distortion for mappings at boundary points of a domain. We consider mappings of the Sobolev and Orlicz-Sobolev classes and some other classes of mappings that do not preserve the boundary of the original domain. We establish estimates of the distortion of distance at boundary points. In particular, under certain conditions on the characteristics of the mappings, we show they are H\"{o}lder continuous in some neighborhoods of the boundary points. In the manuscript we consider both the case of good boundaries and domains with prime ends. We have obtained not only H\"{o}lder-type estimates, but also some more general ones under appropriate (more general) conditions on the characteristic.
