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

open access: yesМатематичні Студії, 2023
The article is devoted to mappings with bounded and finite distortion of planar 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.

Isolated singularities of mappings with the inverse Poletsky inequality

open access: yesМатематичні Студії, 2021
The manuscript is devoted to the study of mappings with finite distortion, which have been actively studied recently. We consider mappings satisfying the inverse Poletsky inequality, which can have branch points.

On compact classes of solutions of Dirichlet problem in simply connected domains

open access: yesМатематичні Студії, 2023
The article is devoted to compactness of solutions of the Dirichlet problem for the Beltrami equation in some simply connected domain. In terms of prime ends, we have proved corresponding results for the case when the maximal dilatations of these ...

On boundary extension of one class of mappings in terms of prime ends

open access: yesМатематичні Студії, 2020
Here we consider the classes of mappings of metric spaces that distort the modulus of families of paths similarly to Poletsky inequality. For domains, which are not locally connected at the boundaries, we obtain results on the boundary extension of the ...

On the convergence of spatial homeomorphisms [PDF]

open access: yesМатематичні Студії, 2013
Various theorems on the convergence of general spatial homeomorphisms are proved and, on this basis, convergence theorems for classes of the so-called ring Q--homeomorphisms are obtained. These results will have wide applications to Sobolev's mappings.

On prime end distortion estimates of mappings with the Poletsky condition in domains with the Poincar´e inequality

open access: yesМатематичні Студії
This article is devoted to the study of mappings with bounded and finite distortion defined in some domain of the Euclidean space. We consider mappings that satisfy some upper estimates for the distortion of the modulus of families of paths, where the ...

On distortion under mappings satisfying the inverse Poletsky inequality

open access: yesМатематичні Студії
As it is known, conformal mappings are locally Lipschitz at inner points of a domain, and quasiconformal (quasiregular) mappings are locally H ̈older continuous.
