On modulus inequality of the order $p$ for the inner dilatation

The article is devoted to mappings with bounded and finite distortion of plane domains. Our investigations are devoted to the connection between mappings of the Sobolev class and upper bounds for the distortion of the modulus of families of paths. For this class, we have proved the Poletsky-type inequality with respect to the so-called inner dilatation of the order~$p\mathrm{.}$ Along the way, we also obtained lower bounds for the modulus distortion under mappings. We separately considered the situations of homeomorphisms and mappings with branch points.
