On the openness and discreteness of mappings with unbounded characteristic of quasiconformality
The paper is devoted to the investigation of the topological properties of space mappings. It is shown that sense-preserving mappings $f : D \rightarrow \overline{\mathbb{R}^n}$ in a domain $D \subset \mathbb{R}^n$, n ≥ 2, which are more general than mappings with bounded distortion, are open and di...

Ukrains’kyi Matematychnyi Zhurnal| Резюме: | The paper is devoted to the investigation of the topological properties of space mappings. It is shown that sense-preserving mappings $f : D \rightarrow \overline{\mathbb{R}^n}$ in a domain $D \subset \mathbb{R}^n$, n ≥ 2, which are more general than
mappings with bounded distortion, are open and discrete if a function Q corresponding to the control of the
distortion of families of curves under these mappings has slow growth in the domain f(D), e.g., if Q has
finite mean oscillation at an arbitrary point $y0 \in f(D)$. |
