A topological analogue of the Borel density theorem
The well known Borel density theorem says that if \(G\) is a connected semisimple Lie group without connected compact subgroup and \(\Gamma\) is a lattice in \(G\) (i.e., \(G/\Gamma\) has finite \(G\)-invariant measure), then \(\Gamma\) is Zariski dense in \(G\). -- The author proves an analogue of this statement replacing the condition ``\(\Gamma\) is a lattice in \(G\)'' by the more general condition ``\(G/\Gamma\) has more than two ends''.
