Huo, Sheng Jin et Wu, Sheng Jian, Hausdorff dimensions of quasilines and differentiability of quasisymmetric homeomorphisms, Acta mathematica Sinica. English series (Print) , 32(4), 2016, pp. 499-506
In this paper, we try to describe the relationship between the differentiability of a quasisymmetric homeomorphism and the local Hausdorff dimension of the quasiline at a point.
