For the open discrete mappings f: D \ {b} → R3 of the domain D ⊂ R3 satisfying relatively general geometric conditions in D \ {b} and having the essential singularity b ∈ R3, we prove the following statement. Let y0 belong to R3 \ f (D \ {b}) and let the inner dilatation KI (x, f) and the outer di...
