Relative topological principality and the ideal intersection property for groupoid C*-algebras

Chris J. Eagle, Gavin Goerke, Marcelo Laca

We introduce the notion of relative topological principality for a family ${H_{α}}$ of open subgroupoids of a Hausdorff étale groupoid $G$ . The C*-algebras $C_{r}^{*} (H_{α})$ of the grou…

$K$ -theory of co-existentially closed continua

Christopher J. Eagle, Joshua Lau

We describe the possible values of $K$ -theory for $C (X)$ when $X$ is a co-existentially closed continuum. As a consequence we also show that all pseudo-solenoids, except perhaps th…
