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 ... -
The homology of the groupoid of the self-similar dihedral group
(Peer reviewed; Journal article, 2022)We compute the K -theory of the C∗ -algebra associated to the self-similar infinite dihedral group, and the homology of its associated étale groupoid. We see that the rational homology differs from the K -theory, strongly ... -

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 ... -
Representability of the local motivic Brouwer degree
(Peer reviewed; Journal article, 2022)We study which quadratic forms are representable as the local degree of a map f : An → An with an isolated zero at 0, following the work of Kass and Wickelgren who established the connection to the quadratic form of Eisenbud, ...
