Three-dimensional sol manifolds and complex kleinian groups

Abstract

We give a topological description of the quotient space $\Omega(G)/G$ in the case $G \subset PSL(3, \mathbb{C})$ is a discrete subgroup acting on $\mathbb{P}^2_\mathbb{C}$ and the maximum number of complex projective lines in general position contained in Kulkarni's limit set, $\Lambda(G)$, is 4. We also give a topological description of the quotient space $\Omega(G)/G$ in the case $G$ a lattice of Heisenberg's group.
