Given an arbitrary infinite 0--1 matrix A having no identically zero rows, we define an algebra OA as the universal C*-algebra generated by partial isometries subject to conditions that generalize, to the infinite case, those introduced by Cuntz and Krieger for finite matrices. We realize OA as the crossed product algebra for a partial dynamical system and, based on this description, we extend to the infinite case some of the main results known to hold in the finite case, namely the uniqueness… Expand

Let (G,P) be a quasi-lattice ordered group and let X be a compactly aligned product system over P of Hilbert bimodules. Under mild hypotheses we associate to X a C*-algebra which we call theExpand
Operator Algebraic Applications in Symbolic Dynamics
By using C∗-correspondences and Cuntz-Pimsner algebras, we associate to every subshift X a C∗-algebra OX, which is a generalization of the Cuntz-Krieger algebra. We show that OX is the universalExpand

We show that the Cuntz-Krieger algebras of infinite graphs and infinite {0,1}-matrices can be approximated by those of finite graphs. We then use these approximations to deduce the main uniquenessExpand

Graph C*-Algebras and Their Ideals Defined by Cuntz-Krieger Family of Possibly Row-Infinite Directed Graphs
Abstract.Let E be a possibly row-infinite directed graph. In this paper, first we prove the existence of the universal C*-algebra C*(E) of E which is generated by a Cuntz-Krieger E-family {se, pv},Expand
Infinite sum relations on universal C*-algebras

We extend the usual theory of universal C*-algebras from generators and relations in order to allow some relations to be described using the strong operator topology. In particular, we can allow someExpand

Inverse semigroups and combinatorial C*-algebras
Abstract.We describe a special class of representations of an inverse semigroup S on Hilbert's space which we term tight. These representations are supported on a subset of the spectrum of theExpand

Partial Representations and Amenable Fell Bundles over Free Groups
We show that a Fell bundle B = {B_t}_{t \in F}, over an arbitrary free group F, is amenable, whenever it is orthogonal (in the sense that B_x^* B_y = 0, if x and y are distinct generators of F) andExpand
Amenability for Fell bundles.
Given a Fell bundle $\B$, over a discrete group $\Gamma$, we construct its reduced cross sectional algebra $C^*_r(\B)$, in analogy with the reduced crossed products defined for C*-dynamical systems.Expand
