# Coarse differentiation and quasi-isometries of a class of solvable Lie groups II

@article{Peng2008CoarseDA, title={Coarse differentiation and quasi-isometries of a class of solvable Lie groups II}, author={Irine Peng}, journal={Geometry \& Topology}, year={2008}, volume={15}, pages={1883-1925} }

In this paper, we continue with the results in [12] and compute the group of quasiisometries for a subclass of split solvable unimodular Lie groups. Consequently, we show that any finitely generated group quasi-isometric to a member of the subclass has to be polycyclic and is virtually a lattice in an abelian-by-abelian solvable Lie group. We also give an example of a unimodular solvable Lie group that is not quasi-isometric to any finitely generated group, as well deduce some quasi-isometric…
