• Finite-rank Bratteli-Vershik diagrams are expansive—a new proof 

      Høynes, Siri-Malén (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 

      Thompson, Peder (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 ...
