Refined geometric characterizations of weak p-quasiconformal mappings
Abstract In this paper, we consider refined geometric characterizations of weak p -quasiconformal mappings $$\varphi :\Omega \rightarrow \widetilde{\Omega }$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mi>φ</mml:mi> <mml:mo>:</mml:mo> <mml:mi>Ω</mml:mi> <mml:mo>→</mml:mo> <mml:mover> <mml:mi>Ω</mml:mi> <mml:mo>~</mml:mo> </mml:mover> </mml:mrow> </mml:math> , where $$\Omega$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>Ω</mml:mi> </mml:math> and $$\widetilde{\Omega }$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mover> <mml:mi>Ω</mml:mi> <mml:mo>~</mml:mo> </mml:mover> </mml:math> are domains in $${\mathbb {R}}^n$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mrow> <mml:mi>R</mml:mi> </mml:mrow> <mml:mi>n</mml:mi> </mml:msup> </mml:math> .
