Graded Locally Finite and Just Infinite Steinberg Algebras
Giuliano Boava, Gilles G. de Castro, Daniel Gonçalves +1
We study graded locally finite and graded just infinite Steinberg algebras of ample Hausdorff groupoids. For gradings by discrete groups induced by a cocycle, we characterize finit…
The dynamical structure of partial group algebras with relations, with applications to subshift algebras
Giuliano Boava, Gilles G. de Castro, Daniel Gonçalves +1
We introduce partial group algebras with relations in a purely algebraic framework. Given a group and a set of relations, we define an algebraic partial action and prove that the r…
Properties Preserved by Groupoid Equivalence
Daniel W. van Wyk, Dana P. Williams
We show that groupoid equivalence preserves a number of groupoid properties such as properness or the property of being topologically principal.
The Primitive Ideal Space of Groupoid C*-Algebras for Groupoids with Abelian Isotropy
Daniel W. van Wyk, Dana P. Williams
We study the topology of the primitive ideal space of groupoid C*-algebras for groupoids with abelian isotropy. Our results include the known results for action groupoids with abel…
Topological full groups of ultragraph groupoids as an isomorphism invariant
Gilles Gonçalves de Castro, Daniel Gonçalves, Daniel W van Wyk
We prove two isomorphism-invariance theorems for groupoids associated with ultragraphs. These theorems characterize ultragraphs for which the topological full group of an associate…
The orbit spaces of groupoids whose -algebras are CCR
Daniel W van Wyk
Let G be second countable locally compact Hausdorff groupoid with a continuous Haar system. We remove the assumption of amenability in a theorem of Clark about groupoids whose $C^*…
