For which rings R is SL_n(R) a virtual duality group
up vote 4 down vote favorite
A famous theorem of Borel and Serre says that if $R$ is the ring of integers in an algebraic number field, then $\text{SL}_n(R)$ satisfies virtual Bieri-Eckmann duality. In other words, there exists
a torsion-free finite-index subgroup $\... | {"url":"http://mathoverflow.net/questions/101624/for-which-rings-r-is-sl-nr-a-virtual-duality-group/101640","timestamp":"2014-04-21T07:57:06Z","content_type":null,"content_length":"50810","record_id":"<urn:uuid:7c9f70f2-5212-41a7-8b32-6f51a1e01352>","cc-path":"CC-MAIN-2014-15/segments/1398223206647.11/warc/CC-MAIN-2014... |
