We consider the boundary-path groupoids of topological higher-rank graphs. We show that the all such groupoids are topologically amenable. We deduce that the C*-algebras of topological higher-rank graphs are nuclear and prove versions of the gauge-invariant uniqueness theorem and the Cuntz-Krieger uniqueness theorem. We then provide a necessary and sufficient condition for simplicity of a topological higher-rank graph C*-algebra, and a condition under which it is also purely infinite. 

Twisted Topological Graph Algebras Are Twisted Groupoid C*-algebras

The second author showed how Katsura's construction of the C*-algebra of a topological graph E may be twisted by a Hermitian line bundle L over the edge space E. The correspondence defining the

Left regular representations of Garside categories I. C*-algebras and groupoids

Left regular representations of Garside categories I. C ∗ -algebras and groupoids

We initiate the study of C ∗ -algebras and groupoids arising from left regular representations of Garside categories, a notion which originated from the study of Braid groups. Every higher rank graph

Aperiodicity Conditions in Topological $k$-Graphs

We give two new conditions on topological $k$-graphs that are equivalent to the Yeend's aperiodicity Condition (A). Each of the new conditions concerns finite paths rather than infinite. We use a

Amenability of groupoids arising from partial semigroup actions and topological higher rank graphs

We consider the amenability of groupoids $G$ equipped with a group valued cocycle $c : G → Q$ with amenable kernel $ c^{ −1} (e)$. We prove a general result which implies, in particular, that $G$ is

Co‐universal algebras associated to product systems, and gauge‐invariant uniqueness theorems

Let (G, P) be a quasi‐lattice ordered group, and let X be a product system over P of Hilbert bimodules. Under mild hypotheses, we associate to X a C*‐algebra which is co‐universal for injective Nica

Cocycles on Deaconu-Renault Groupoids and KMS States for Generalized Gauge Dynamics

We consider higher-rank Deaconu-Renault groupoids, constructed from a finite number of commuting local homeomorphisms acting on a compact metric space, and study generalized Ruelle operators and $

Cuntz's $ax+b$-semigroup C*-algebra over $\mathbb{N}$ and product system C*-algebras

We investigate $C^*$-algebras associated with row-finite topological higher-rank graphs with no source, which are based on product system $C^*$-algebras. We prove the Cuntz-Krieger uniqueness

Analogues of Leavitt path algebras for higher-rank graphs

Directed graphs and their higher-rank analogues provide an intuitive framework to study a class of C∗-algebras which we call graph algebras. The theory of graph algebras has been developed by a

Product systems over Ore monoids

We interpret the Cuntz-Pimsner covariance condition as a nondegeneracy condition for representations of product systems. We show that Cuntz-Pimsner algebras over Ore monoids are con- structed through



Topological higher-rank graphs and the $C^*$-algebras of topological 1-graphs

We introduce the notion of a topological higher-rank graph, a unified generalization of the higher-rank graph and the topological graph. Using groupoid techniques, we define the Toeplitz and

Groupoid models for the C*-algebras of topological higher-rank graphs

We provide groupoid models for Toeplitz and Cuntz-Krieger algebras of topological higher-rank graphs. Extending the groupoid models used in the theory of graph algebras and topological dynamical

A class of C*-algebras generalizing both graph algebras and homeomorphism C*-algebras I, fundamental results

We introduce a new class of C*-algebras, which is a generalization of both graph algebras and homeomorphism C*-algebras. This class is very large and also very tractable. We prove the so-called


We show that the method to construct C*-algebras from topological graphs, introduced in our previous paper, generalizes many known constructions. We give many ways to make new topological graphs from

Groupoids and C * -algebras for categories of paths

In this paper we describe a new method of defining C*-algebras from oriented combinatorial data, thereby generalizing the constructions of algebras from directed graphs, higher-rank graphs, and

Higher-Rank Graph C *-Algebras: An Inverse Semigroup and Groupoid Approach

AbstractWe provide inverse semigroup and groupoid models for the Toeplitz and Cuntz-Krieger algebras of finitely aligned higher-rank graphs. Using these models, we prove a uniqueness theorem for the

Simplicity of C*‐algebras associated to higher‐rank graphs

We prove that if Λ is a row‐finite k‐graph with no sources, then the associated C*‐algebra is simple if and only if Λ is cofinal and satisfies Kumjian and Pask's aperiodicity condition, known as


We develop a theory of graph C -algebras using path groupoids and inverse semigroups. Row finiteness is not assumed so that the theory applies to graphs for which there are vertices emitting a

On higher rank graph C ∗ -algebras

Given a row-finite k-graph Λ with no sources we investigate the K-theory of the higher rank graph C *-algebra, C * (Λ). When k = 2 we are able to give explicit formulae to calculate the K-groups of C
