Partially Bounded Transformations have Trivial Centralizer

Proc. Amer. Math. Soc. 146 (2018), no. 12, 5112-5127 We prove that for infinite rank-one transformations satisfying a property called "partial boundedness," the only commuting transformations are powers of the original transformation. This shows that a large class of infinite measure-preserving rank-one transformations with bounded cuts have trivial centralizers. We also characterize when partially bounded transformations are isomorphic to their inverse.
