Finite-rank Bratteli-Vershik diagrams are expansive—a new proof
(Journal article; Peer reviewed, 2017)Downarowicz and Maass (Ergod. Th. and Dynam. Sys. 28 (2008), 739–747) proved that the Cantor minimal system associated to a properly ordered Bratteli diagram of finite rank is either an odometer system or an expansive ... -
Minimal complexes of cotorsion flat modules
(Journal article; Peer reviewed, 2019)Let R be a commutative noetherian ring. We give criteria for a complex of cotorsion flat R-modules to be minimal, in the sense that every self homotopy equivalence is an isomorphism. To do this, we exploit Enochs' description ...
