On Invertibility of Sobolev Mappings
Leonid V. Kovalev, Jani Onninen
We prove local and global invertibility of Sobolev solutions of certain differential inclusions which prevent the differential matrix from having negative eigenvalues. Our results…

Dynamics of quasiconformal fields
Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen
A uniqueness theorem is established for autonomous systems of ODEs, , where is a Sobolev vector field with additional geometric structure, such as delta-monoticit…

On injectivity of quasiregular mappings
Tadeusz Iwaniec, Leonid V. Kovalev, Jani Onninen
We give sufficient conditions for a planar quasiregular mapping to be injective in terms of the range of the differential matrix.
