Abstract
For the mappings f : D → D
�
, D, D
� ⊂ Rn, n ≥ 2, satisfying certain geometric conditions
in the fixed domain D, we have proved estimates of the form KI (x, f) ≤ Q(x) almost everywhere, where
KI (x, f) is the inner dilatation of f at a point x, and Q(x) is a fixed realvalued function responsible for
the “control” over a distortion of the families of curves in D at a mapping f.
