Streszczenie
Z. Zhou et al. (2012) proved that in a Teichmüller equivalence class, there exists an extremal quasiconformal mapping with a weakly non-decreasable dilatation. In this paper, we prove that if a Teichmüller class contains more than one extremal dilatation, then it contains infinitely many weakly non-decreasable extremal dilatations.
