Circle correspondence C ∗ -algebras

چکیده
We investigate Cuntz-Pimsner C∗-algebras associated with certain correspondences of the unit circle T. We analyze these C∗-algebras by analogy with irrational rotation algebras Aθ and Cuntz algebras On. We construct a Rieffel type projection, study the fixed point algebras of certain actions of finite groups, and calculate the entropy of a certain endomorphism. We also study the induced map of the dual action of the gauge action on K-groups.

Classification of simple C * - algebras and higher dimensional noncommutative tori
We show that unital simple C-algebras with tracial topological rank zero which are locally approximated by subhomogeneous C-algebras can be classified by their ordered K-theory. We apply this classification result to show that certain simple crossed products are isomorphic if they have the same ordered K-theory. In particular, irrational higher dimensional noncommutative tori of the form C(T)×θ...
متن کاملC∗-algebras Associated Noncommutative Circle and Their K-theory
In this article we investigate the universal C∗-algebras associated to certain 1dimensional simplicial flag complexes which describe the noncommutative circle. We denote it by S 1 . We examine the K-theory of this algebra and the subalgebras S nc 1 /Ik, Ik . Where Ik, for each k, is the ideal in S 1 generated by all products of generators hs containing at least k + 1 pairwise different generato...
متن کاملRank-two Graphs Whose C∗-algebras Are Direct Limits of Circle Algebras
We describe a class of rank-2 graphs whose C∗-algebras are AT algebras. For a subclass which we call rank-2 Bratteli diagrams, we compute the K-theory of the C∗-algebra. We identify rank-2 Bratteli diagrams whose C∗-algebras are simple and have real-rank zero, and characterise the K-invariants achieved by such algebras. We give examples of rank-2 Bratteli diagrams whose C∗-algebras contain as f...
متن کاملA Classification Theorem for Direct Limits of Extensions of Circle Algebras by Purely Infinite C*-algebras
We give a classification theorem for a class of C*-algebras which are direct limits of finite direct sums of E0-algebras. The invariant consists of the following: (1) the set of Murray-von Neumann equivalence classes of projections; (2) the set of homotopy classes of hyponormal partial isometries; (3) a map d; and (4) total K-theory.
متن کاملThe C*-algebra of a vector bundle and fields of Cuntz algebras
We study the Pimsner algebra associated with the module of continuous sections of a Hilbert bundle, and prove that it is a continuous bundle of Cuntz algebras. We discuss the role of such Pimsner algebras w.r.t. the notion of inner endomorphism. Furthermore, we study bundles of Cuntz algebras carrying a global circle action, and assign to them a class in the representable KK -group of the zero-...
