Abstract

If Γ\Gamma is a discrete subgroup of PSL(3,C)PSL(3,\Bbb{C}), it is determined the equicontinuity region Eq(Γ)Eq(\Gamma) of the natural action of Γ\Gamma on PC2\Bbb{P}^2_\Bbb{C}. It is also proved that the action restricted to Eq(Γ)Eq(\Gamma) is discontinuous, and Eq(Γ)Eq(\Gamma) agrees with the discontinuity set in the sense of Kulkarni whenever the limit set of Γ\Gamma in the sense of Kulkarni, Λ(Γ)\Lambda(\Gamma), contains at least three lines in general position. Under some additional hypothesis, it turns out to be the largest open set on which Γ\Gamma acts discontinuously. Moreover, if Λ(Γ)\Lambda(\Gamma) contains at least four complex lines and Γ\Gamma acts on PC2\Bbb{P}^2_\Bbb{C} without fixed points nor invariant lines, then each connected component of Eq(Γ)Eq(\Gamma) is a holomorphy domain and a complete Kobayashi hyperbolic space.
