Dimension of asymptotic cones in Lie groups

Yves de Cornulier of IRMAR Institute in Rennes, France

To every metric space X is associated its asymptotic cone, which is a topological space reflecting the large scale geometry of X. When X is a connected Lie group, we compute the dimension of its asymptotic cone. The formula makes use of the exponential radical, introduced by Osin a few years ago.
