摘要

摘要在具有加倍测度的完备度量空间中，证明了连接两个集合的曲线族和分离两个集合的曲面族的模的对偶关系。然后我们应用这一点来证明拟共形映射可以用它们准保持某些曲面族的模量这一事实来表征。

Duality of Moduli and Quasiconformal Mappings in Metric Spaces

Abstract We prove a duality relation for the moduli of the family of curves connecting two sets and the family of surfaces separating the sets, in the setting of a complete metric space equipped with a doubling measure and supporting a Poincaré inequality. Then we apply this to show that quasiconformal mappings can be characterized by the fact that they quasi-preserve the modulus of certain families of surfaces.
