The K-theory of Cuntz-Krieger algebras for infinite matrices
Ruy Exel, Marcelo Laca
We compute the K-theory of the Cuntz-Krieger C^*-algebras associated to infinite matrices.

Finite dimensional representations of the soft torus
Soren Eilers, Ruy Exel
The soft tori constitute a continuous deformation, in a very precise sense, from the commutative C*-algebra C(T^2) to the highly non-commutative C*-algebra C*(F_2). Since both of t…

Cuntz-Krieger algebras for infinite matrices
Ruy Exel, Marcelo Laca
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…
