Topological median algebra structures on ER homology manifolds I: local cubulation

Mladen Bestvina, Kenneth Bromberg, Michah Sageev

We study topological median algebra structures on Euclidean spaces and, more generally, ER homology manifolds. We show that all such median structures have a local CAT(0) cubulatio…

Disintegrating the curve complex

Mladen Bestvina, Kenneth Bromberg, Alexander J. Rasmussen

We study a finite sequence of graphs, beginning with the curve graph and ending with a graph quasi-isometric to a tree. There is a Lipschitz map from one graph in the sequence to t…

Ergodic Measures in Strata

Mladen Bestvina, Jon Chaika, Sebastian Hensel

We determine the number of ergodic measures in each stratum of geodesic laminations on a surface.

Classification of Stable Surfaces with respect to Automatic Continuity

Mladen Bestvina, George Domat, Kasra Rafi

We provide a complete classification of when the homeomorphism group of a stable surface, , has the automatic continuity property: Any homomorphism from Homeo to a separabl…

Nonunique Ergodicity on the Boundary of Outer space

Mladen Bestvina, Elizabeth Field, Sanghoon Kwak

To an -tree in the boundary of Outer space, we associate two simplices: the simplex of projective length measures, and the simplex of projective dual currents. For both…

On the geometry of the free factor graph for

Mladen Bestvina, Martin R. Bridson, Richard D. Wade

Let be a pseudo-Anosov diffeomorphism of a compact (possibly non-orientable) surface with one boundary component. We show that if is the boundary word, $ϕ\in…
