Webto matrix groups, i.e., closed subgroups of general linear groups. One of the main results that we prove shows that every matrix group is in fact a Lie subgroup, the proof being modelled on that in the expos-itory paper of Howe [5].

Let Γg denote its fundamental group, and Rg the representation space Hom(Γg,PSL(2,R)). Elements of Rg are determined by the images of the 2ggenerators of Γg, subject to the single relation defining Γg. It follows that Rg has a real algebraic structure (see e.g. [1]).

We could equally well say that: A linear group is a closed subgroup of GL(n,C). For as we shall see shortly, GL(n,C) has an isomorphic im-age as a closed subgroup of GL(2n,R); while conversely it is clear that GL(n,R) can be regarded as a closed subgroup of GL(n,C). 2.
