Normal Congruence Subgroups of The Bianchi Groups and Related Groups |
| I submitted this thesis to the Department of Mathematics in the Faculty of Science at the University of Glasgow in April 1999, and was awarded a Ph.D. on December 3rd 1999. The only parts published came from Chapter 4, which were published in Archiv der Mathematik, 75 as Normal Subgroups of prescribed order and zero level of subgoups of the Bianchi groups.
