While the proof of the general Rank Theorem uses an involved reduction theory due to Harder, by imposing the restrictions that the group is split and that S has only two places, one can instead make use of the theory of twin buildings."--Page 4 of cover 650 0$aBuildings (Group theory) 650 0$aFinite geometries 856 40$uhttp://link.springer.com/book/10.1007/978-3-319-06477-2$zAn electronic book accessible through the World Wide Web 907 $a.b14305756$b03-03-22$c01-08-16 912 $a991003265589707536 996 $aFiniteness properties of arithmetic groups acting on twin buildings$91392283 997 $aUNISALENTO 998 $ale013$b01-08-16$cm$d@ $e-$feng$gsz $h0$i0
