Quasiisometries of negatively curved homogeneous manifolds associated with Heisenberg groups
Xiangdong Xie
We study quasiisometries between negatively curved homogeneous manifolds associated with diagonalizable derivations on Heisenberg algebras. We classify these manifolds up to quasii…

Some examples of quasiisometries of nilpotent Lie groups
Xiangdong Xie
We construct quasiisometries of nilpotent Lie groups. In particular, for any simply connected nilpotent Lie group N, we construct quasiisometries from N to itself that is not at fi…
