Abstract
For a subtype of map**s with finite distortion f : D → D′, D, D′ ⊂ ℝn; n ≥ 2; which admit the existence of branch points, a modular inequality playing an essential role in the study of various problems of planar and spatial map**s is established. As an application, the problem of removal of isolated singularities of open discrete map**s with finite length distortion is investigated.
