Exel's crossed product for non-unital C*-algebras
We consider a family of dynamical systems (A,alpha,L) in which alpha is an
endomorphism of a C*-algebra A and L is a transfer operator for \alpha. We
extend Exel's construction of a crossed product to cover non-unital algebras A,
and show that the C*-algebra of a locally finite graph can be realised as one
of these crossed products. When A is commutative, we find criteria for the
simplicity of the crossed product, and analyse the ideal structure of the
crossed product.Comment: 22 page
Politically engaged artistic practice: Strategies and tactics
This paper explores political forms of artistic practice operating within Tate Exchange broadly and within the authors’ creative practice specifically. It identifies the tensions and obstacles inherent to socially engaged artistic practice and forms of expertise, and proposes a method of practice that is grounded in prefiguration and solidarity
Strong Shift Equivalence of -correspondences
We define a notion of strong shift equivalence for -correspondences and
show that strong shift equivalent -correspondences have strongly Morita
equivalent Cuntz-Pimsner algebras. Our analysis extends the fact that strong
shift equivalent square matrices with non-negative integer entries give stably
isomorphic Cuntz-Krieger algebras.Comment: 26 pages. Final version to appear in Israel Journal of Mathematic
