Seade %J Mathematics %D 2011 %I arXiv %X Classical Kleinian groups are discrete subgroups of $PSL(2,\C)$ acting on the complex projective line $\P^1$, which actually coincides with the Riemann sphere, with non-empty region of discontinuity. These can also be regarded as the monodromy groups of certain differential equations. These groups have played a major role in many aspects of mathematics for decades, and also in physics. It is thus natural to study discrete subgroups of the projective group $PSL(n,\C)$, $ n > 2$. Surprisingly, this is a branch of mathematics which is in its childhood, and in this article we give an overview of it. %U http://arxiv.org/abs/1110.2674v1
