Sei k ein algebraischer Zahlkörper und sei D eine zentrale Divisionsalgebra endlicher Dimension über k. Der Kern der reduzierten Norm-Abbildung nrd:M(2,D)-> k definiert eine lineare algebraische k-Gruppe G, die im Allgemeinen mit SL_2(D) bezeichnet wird. Eine maximale Ordnung L in D induziert eine arithmetische Untergruppe Gamma=SL_2(L) in SL_2(D). Diese operiert auf einem homogenen Raum X, der durch eine Lie-Gruppe, die G zugeordnet ist, definiert wird. Der Quotientenraum X/Gamma ist nicht kompakt, kann aber in natürlicher Weise, nach Borel und Serre, kompaktifiziert werden. Diese Kompaktifizierung \overline{X}/Gamma erhält man, indem man endlich viele Randkomponenten e'(P) hinzuüugt, eine für jede eigentliche parabolische Untergruppe P ...
