On the theorem of wan for K-quasiconformal hyperbolic harmonic self mappings of the unit disk

We give a new glance to the theorem of Wan (Theorem 1.1) which is related to the hyperbolic bi-Lipschicity of the K-quasiconformal, K ≥ 1, hyperbolic harmonic mappings of the unit disk D onto itself. Especially, if f is such a mapping and f(0) = 0, we obtained that the following double inequality is...
