Classification of sectors of the Cuntz algebras by graph invariants

چکیده
A unitary equivalence class of endomorphisms of a unital C∗-algebra A is called a sector of A. We introduced permutative endomorphisms of the Cuntz algebra ON in the previous work. Branching laws of permutative representations of ON by them are computed by directed regular graphs. In this article, we classify sectors associated with permutative endomorphisms of ON by their graph invariants concretely.

A Class of Limit Algebras Associated with Directed Graphs
Every directed graph defines a Hilbert space and a family of weighted shifts that act on the space. We identify a natural notion of periodicity for such shifts and study their C∗algebras. We prove the algebras generated by all shifts of a fixed period are of Cuntz-Krieger and Toeplitz-Cuntz-Krieger type. The limit C∗-algebras determined by an increasing sequence of positive integers, each divid...
متن کاملCuntz-Krieger algebras of infinite graphs and matrices
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 uniqueness theorems for CuntzKrieger algebras and to compute their K-theory. Since the finite approximating graphs have sinks, we have to calculate the K-theory of Cuntz-Krieger algebras of graphs with sinks, an...
متن کاملStrongly Self-absorbing C * -algebras
Say that a separable, unital C *-algebra D ≇ C is strongly self-absorbing if there exists an isomorphism ϕ : D → D ⊗ D such that ϕ and id D ⊗ 1 D are approximately unitarily equivalent *-homomorphisms. We study this class of algebras, which includes the Cuntz algebras O 2 , O∞, the UHF algebras of infinite type, the Jiang–Su algebra Z and tensor products of O∞ with UHF algebras of infinite type...
متن کاملCuntz Semigroups of Compact-Type Hopf C*-Algebras
The classical Cuntz semigroup has an important role in the study of C*-algebras, being one of the main invariants used to classify recalcitrant C*-algebras up to isomorphism. We consider C*-algebras that have Hopf algebra structure, and find additional structure in their Cuntz semigroups. We show that in many cases, isomorphisms of Cuntz semigroups that respect this additional structure can be ...
متن کاملAbelian core of graph algebras
We introduce a certain natural abelian C*-subalgebra of a graph C*-algebra, which has functorial properties that can be used for characterizing injectivity of representations of the ambient C*-algebra. In particular, a short proof of the Cuntz-Krieger Uniqueness Theorem, for graphs that may have loops without entries, is given. Graph C*-algebras are interesting objects with a structure that can...
