Abstract: | We study relations between the quantity characterizing the distortion of families of curves under a given mapping and the
structure of the branch point set of this mapping. For n ⩽ 3 we establish that the image of the branch point set of an open discrete mapping with an isolated essential singularity
is an unbounded set in Rn provided that the mapping satisfies certain geometric conditions controlling the distortion of concentric annuli centered
at this point. |
