Title: Tail equivalence of unicorn paths.
Abstract: Let S be an orientable surface of finite type. Using Pho-On's infinite unicorn paths, we prove hyperfiniteness of the orbit equivalence relation coming from the action of the mapping class group of S on the Gromov boundary of the arc graph of S. This is joint work with Marcin Sabok.
