Abstract:
The boundary behavior of closed open discrete mappings of Sobolev and Orlicz–Sobolev classes in $\mathbb R^n$, $n\ge3$, is studied. It is proved that a mapping $f$ mentioned above has a continuous extension to a boundary point $x_0\in\partial D$ of a domain $D\subset\mathbb R^n$ whenever its inner dilatation of order $\alpha>n-1$ has a majorant of finite mean oscillation class at the point in question. Another sufficient condition for continuous extension of mappings is the divergence of some integral. Some results on continuous extension of these mappings to an isolated boundary point are also proved.
