Abstract:
We continue the study of multivalued mappings with the BAD (bounded angular distortion) property which was initiated in the author's works in 2018. Using the technique of ultrafilters, we obtain a full description for the mutual adherence domains of the images of points under mappings of BAD class. We exhibit the example that illustrates all possible cases in the general formula for adherence domains.
