Regular ideals, Ideal Intersections and Quotients II

Jonathan H. Brown, Adam H. Fuller, David R. Pitts +1

Let $B \subseteq A$ be a regular inclusion of C*-algebras satisfying the ideal intersection property and with a faithful invariant pseudo-expectation. A complete description of the…

Fourier coefficients and rapid decay in reduced groupoid C*-algebras

Adam H. Fuller, Pradyut Karmakar

Let $I^£ \to G$ be a twist over a locally compact Hausdorff Ã©tale groupoid $G$ . Given $f$ in the reduced C $^{*}$ -algebra $C_{r}^{*} (I^£; G)$ with open support $U \subseteq G$ we ask…

Intermediate Subalgebras of Cartan embeddings in rings and C*-algebras

Jonathan H. Brown, Lisa Orloff Clark, Adam H. Fuller

Let $D \subseteq A$ be a quasi-Cartan pair of algebras. Then there exists a unique discrete groupoid twist $I^£ \to G$ whose twisted Steinberg algebra is isomorphic to $A$ in a way t…
