Abstract

Let \(\{f_n:\mathbb {D}\rightarrow \mathbb {D}\}\) be a sequence of K-quasiconformal harmonic maps on the unit disk \(\mathbb {D}\) with respect to the Poincaré metric. It is known that there is a subsequence of \(\{f_n\}\) that uniformly converges on \(\overline{\mathbb {D}}\), and the limit function is either a K-quasiconformal harmonic map of the Poincaré disk or a constant. In this paper, it is shown that, if the limit function is not a constant, the subsequence can be chosen such that its derivative sequence of arbitrary order uniformly converges to the corresponding derivative of the limit function on compact subsets of \(\mathbb {D}\).
