Abstract
In this paper, we give discreteness criteria of subgroups of the special linear group on ℚ p or ℂ p in two and higher dimensions. Jørgensen’s inequality gives a necessary condition for a non-elementary group of Möbius transformations to be discrete. We give a version of Jørgensen’s inequality for SL(m,ℂ p ).
