    Quasiconformal groups with small dilatation. I (English)
    0 references
    Quasiconformal Fuchsian groups with small dilatation are studied in this paper. A Jørgensen-type inequality in all dimensions is established for such a class of groups. It is shown that discreteness persists to the limit under algebraic convergence. Such groups are discrete if and only if every two generator subgroup is discrete.
