Реферат: The class of multivalued mappings with bounded angular distortion (BAD) property in metric spaces can be considered as a multivalued analog for quasimöbius mappings. We study the connections between quasimeromorphic self-mappings of X = R ̄^n and multivalued mappings F : X → 2X with BAD property. The main result of the paper concerns the multivalued mappings F : D → 2^C with BAD property of a domain D ⊂ C ̄. If the image F(x) of each point x ∈ D is either a point or a continuum with bounded turning then F is proved to be a single-valued quasimobius mapping. The crucial point in the proof of this result is the local connectedness of the set F(X) for the multivalued continuous mapping F : X → 2^Y with BAD property. We obtain sufficient conditions providing F(X) to have local connectedness or bounded turning property in the most general case.
