Coarse differentiation and quasi-isometries of a class of solvable Lie groups II
Irine Peng
In this paper, we continue with the results in \cite{Pg} and compute the group of quasi-isometries for a subclass of split solvable unimodular Lie groups. Consequently, we show tha…

Bilipschitz maps of boundaries of certain negatively curved homogeneous spaces
Tullia Dymarz, Irine Peng
In this paper we study certain groups of bilipschitz maps of the boundary minus a point of a negatively curved space that is an abelian-by-cyclic solvable Lie group, where the exte…

Coarse differentiation and quasi-isometries of a class of solvable Lie groups I
Irine Peng
This is the first of two papers which aim to understand quasi-isometries of a subclass of unimodular split solvable Lie groups. In the present paper, we show that locally (in a coa…
