Abstract: In analogy to the mapping class group acting on the Teichmuller space, we have the group of outer automorphisms of the free group acting on Culler-Vogtmann's `Outer space'. The limit sets of geodesics in Teichmuller space exhibit very interesting and varied phenomena with respect to the Teichmuller metric, Thurston metric and Weil Petersson metric. In this talk, we will look for similar results for `folding/unfolding' paths in Outer space.
