Quasisymmetry and solidity of quasiconformal maps in metric spaces

This paper is devoted to the study of the broad problem of deriving global metric properties from local quasiconformality in metric spaces. In particular, we show that, under certain regularity and connectivity conditions, a quasiconformal map between metric spaces is weakly (L,M)-quasisymmetric. Furthermore, such a map is solid if the metric spaces are complete. These extend and generalize some well known results in Euclidean as well as metric spaces.
