摘要：In this paper, we establish a characterization of freely quasiconformal mappings in real Banach spaces. This characterization is in terms of the geometric moduli of rings which was introduced by Tukia-Vaisala in 2021. As an application, we obtain a generalization of geometric characterizations of quasiconformal mappings in Rn. Also, we get characterizations for a freely quasiconformal mapping to be quasisymmetric and quasimobius, respectively. These characterizations are in terms of the geometric moduli of rings as well.
