Event description: 

Every non-elementary subgroup of $PSL(2,\mathbf{C})$
generated by two parabolic transformations is determined up to
conjugacy by a non-zero complex number, $\lambda$ and each
$\lambda\neq 0$ determines a two-parabolic generator group. I will
discuss a structure theorem for the space of all $\lambda$, that is,
for the full representation space (modulo conjugacy) of
non-elementary two-parabolic generator groups, including both the
discrete and non-discrete groups. The discrete groups include, of
course, Kleinian groups both manifold and orbifold groups.
