Path-connectivity of Thick Laminations, and Markov Processes with Thick Limit Sets
Abstract
A lamination $λ$ is $ε$-thick (with respect to a basepoint $X$), if the Teichmüller ray from $X$ in the direction of $λ$ stays in the $ε$-thick part. We show that, for surfaces of high enough genus, any two $ε$-thick laminations can be joined by a path of $δ$-thick laminations. As a consequence, we show that the Morse boundary of the mapping class group is path-connected. Furthermore, we construct a subshift of finite type on the mapping class group, whose limit set consists only of thick laminations and is path-connected.
