Nontraditional models of -Cartan pairs
Jonathan H. Brown, Elizabeth Gillaspy
This paper explores the tension between multiple models and rigidity for groupoid -algebras. We begin by identifying -Cartan subalgebras inside twisted groupoid -a…
The local bisection hypothesis for twisted groupoid C*-algebras
Becky Armstrong, Jonathan H. Brown, Lisa Orloff Clark +4
In this note, we present criteria that are equivalent to a locally compact Hausdorff groupoid being effective. One of these conditions is that satisfies the "C*-algebraic l…
Regular ideals, ideal intersections, and quotients
Jonathan H. Brown, Adam H. Fuller, David R. Pitts +1
Let be an inclusion of C-algebras. We study the relationship between the regular ideals of and regular ideals of . We show that if is a r…
Regular ideals of graph algebras
Jonathan H. Brown, Adam H. Fuller, David R. Pitts +1
Let be the graph C-algebra of a row-finite graph . We give a complete description of the vertex sets of the gauge-invariant regular ideals of . It is shown…
Intermediate C*-algebras of Cartan Embeddings
Jonathan H. Brown, Ruy Exel, Adam H. Fuller +2
Let be a C-algebra and let be a Cartan subalgebra of . We study the following question: if is a C-algebra such that , is a Car…
Graded C*-algebras and twisted groupoid C*-algebras
Jonathan Brown, Adam Fuller, David Pitts +1
Let -algebra that is acted upon by a compact abelian group. We show that if the fixed-point algebra of the action contains a Cartan subalgebra satisfying an appropriate re…
