Limit sets of unfolding paths in Outer space

By Radhika Gupta

Teichmuller geodesic rays exhibit an odd behaviour in that they do not always converge in the Thurston boundary. In contrast, folding rays in Outer space of a free group always converge in its boundary. In this talk, I will present a construction of an ‘unfolding path’ in Outer space that converges to a 1-simplex in the boundary, corresponding to a non-uniquely ergodic and non-uniquely ergometric arational tree. This is joint work with Mladen Bestvina and Jing Tao.
