Continuous cocycle superrigidity for the full shift over a finitely generated torsion group
David Bruce Cohen
Chung and Jiang showed that, if a one ended group contains an infinite order element, then every continuous cocycle over the full shift on that group, taking values in a discrete g…

Strongly aperiodic subshifts of finite type on hyperbolic groups
David Bruce Cohen, Chaim Goodman-Strauss, Yo'av Rieck
We prove that a hyperbolic group admits a strongly aperiodic subshift of finite type if and only if it has at most one end.
