关于平面内有限畸变映射的边界表现

On boundary behavior of mappings with finite distortion in the plane

Denis Kovtonyuk, Igor Petkov, Vladimir Ryazanov

摘要:

本文研究了拟共形映射在平面上的一种自然推广,即所谓的下Q-同胚的边界表现。特别地,得到了函数Q(z)的一系列有效条件,这些条件是给定的映射通过素端到边界的同胚扩张。所发展的理论被应用于Iwaniec的有限变形映射,也被应用于Beltrami方程的解,以及被应用于已知的等距映射和拟等距映射类的一个深远的推广-Lipschitz映射。

英文摘要:

In the present paper, it was studied the boundary behavior of the so-called lower Q-homeomorphisms in the plane that are a natural generalization of the quasiconformal mappings. In particular, it was found a series of effective conditions on the function Q(z) for a homeomorphic extension of the given mappings to the boundary by prime ends. The developed theory is applied to mappings with finite distortion by Iwaniec, also to solutions of the Beltrami equations, as well as to finitely bi--Lipschitz mappings that a far--reaching extension of the known classes of isometric and quasiisometric mappings.
