PreprintInfinite generation of noncocompact lattices on rightangled buildingsAnne Thomas and Kevin WortmanAbstractLet \(\Gamma\) be a noncocompact lattice on a locally finite regular rightangled building \(X\). We prove that if \(\Gamma\) has a strict fundamental domain then \(\Gamma\) is not finitely generated. We use the separation properties of subcomplexes of \(X\) called treewalls.
