On isolated singularities of mappings with inverse moduli inequalities

Abstract

We consider open discrete mappings that satisfy the modulus condition of the inverse Poletsky inequality type. We study the case when the majorant in it is integrable, or more generally, has finite averages over infinitesimal spheres. We proved that such mappings have a continuous extension to an isolated point of the boundary of some domain without any a priori requirements on the corresponding mapped domain for integrable majorants. In the case of majorants, integrable on spheres, we require only the boundedness of the mapped domain. We do not require any other topological conditions on the mappings.
