Dimension of asymptotic cones of Lie groups
IRMAR, Campus de Beaulieu, 35042 Rennes Cedex, France cornulier{at}phare.normalesup.org
We compute the covering dimension of the asymptotic cone of a connected Lie group. For simply connected solvable Lie groups, this is the codimension of the exponential radical.
As an application of the proof, we give a characterization of connected Lie groups that quasi-isometrically embed into a nonpositively curved metric space.
