On random walks on the mapping class group

Ursula Hamenstädt

We define an electrification of the curve graph of a surface S of finite type and use it to identify the Poisson boundary of a random walk on the mapping class group of S with some…

An EZ-structure for the mapping class group

Ursula Hamenstädt

We construct a boundary for the mapping class group Mod(S) of a surface S of finite type. The action of Mod(S) on this boundary is minimal, strongly proximal and topologically free…

Periodic orbits in the thin part of strata

Ursula Hamenstädt

Let S be a closed oriented surface of genus with punctures and . Let be a connected component of a stratum in the moduli space Q(S) of area on…

Spotted disk and sphere graphs

Ursula Hamenstädt

The disk graph of a handlebody H of gneus with marked points on the boundary is the graph whose vertices are isotopy classes of disks disjoint from the marked p…

Geometry of the mapping class groups I: Boundary amenability

Ursula Hamenstaedt

We construct a geometric model for the mapping class group M of a non-exceptional oriented surface of finite type and use it to show that the action of M on the compact Hausdorff s…

Spectral convergence of manifold pairs

K. Fissmer, U. Hamenstaedt

We investigate the spectra of a family of pairs (M_i,A_i) consisting of a complete Riemannian manifold M_i and a closed subset A_i and which converge in the Lipschitz topology to a…
