Grushin平面上的拟共形映射

Quasiconformal mappings on the Grushin plane

Chris Gartland, Derek Jung, Matthew Romney

摘要:

我们证明了Grushin平面的自同胚是拟对称的当且仅当它是度量拟共形的,当且仅当它是几何拟共形的。在我们的论点的主要步骤,我们表明,一个准对称参数化的Grushin平面的欧氏平面也必须是几何拟共形的。我们还讨论了拟共形映射的欧氏理论的某些方面,如几乎每一条紧曲线上的绝对连续性,在Grushin的情况下不满足。

英文摘要:

We prove that a self-homeomorphism of the Grushin plane is quasisymmetric if and only if it is metrically quasiconformal and if and only if it is geometrically quasiconformal. As the main step in our argument, we show that a quasisymmetric parametrization of the Grushin plane by the Euclidean plane must also be geometrically quasiconformal. We also discuss some aspects of the Euclidean theory of quasiconformal maps, such as absolute continuity on almost every compact curve, not satisfied in the Grushin case.
