Nonamenable subforests of multi-ended quasi-pmp graphs

Ruiyuan Chen, Grigory Terlov, Anush Tserunyan

We prove the a.e. nonamenability of locally finite quasi-pmp Borel graphs whose every component admits at least three nonvanishing ends with respect to the underlying Radon--Nikody…

Structural, point-free, non-Hausdorff topological realization of Borel groupoid actions

Ruiyuan Chen

We extend the Becker--Kechris topological realization and change-of-topology theorems for Polish group actions in several directions. For Polish group actions, we prove a single re…
