Abstract

The homology of rank one linear groups (SL2, PGL2) often can be computed via the action of the group on a suitable simplicial complex. There is the well-known tiling of the hyperbolic plane by SL2(ℤ)-translates of an ideal triangle (see, e.g. [21], p. 215) and there is the Bruhat-Tits tree associated to a field with discrete valuation. Often, the action implies something about the structure of the group such as the existence of an amalgamated free product decomposition.
