Isomorphisms among monodromy groups and applications to lattices in PU(1,2)
John Sauter · Pacific Journal of Mathematics · 1990
The discreteness of some monodromy groups in PU( 1,2) is proved.G. D. Mostow's conjecture on a necessary and sufficient condition for the discreteness of monodromy subgroups of PU( 1, 2) is established.Some isomorphisms and inclusion relations among the monodromy groups are given.
