چکیده

We introduced a non-symmetric tensor product of any two states or any two representations of Cuntz-Krieger algebras associated with a certain non-cocommutative comultiplication in previous our work. In this paper, we show that a certain set of KMS states is closed with respect to the tensor product. From this, we obtain formulae of tensor product of type III factor representations of Cuntz-Krieger algebras which is different from results of the tensor product of factors of type III.

Classification and realizations of type III factor representations of Cuntz-Krieger algebras associated with quasi-free states

We completely classify type III factor representations of CuntzKrieger algebras associated with quasi-free states up to unitary equivalence. Furthermore, we realize these representations on concrete Hilbert spaces without using GNS construction. Free groups and their type II1 factor representations are used in these realizations.

C-bialgebra defined by the direct sum of Cuntz-Krieger algebras

Let CK∗ denote the C ∗-algebra defined by the direct sum of all Cuntz-Krieger algebras. We introduce a comultiplication ∆φ and a counit ε on CK∗ such that ∆φ is a nondegenerate ∗-homomorphism from CK∗ to CK∗ ⊗ CK∗ and ε is a ∗-homomorphism from CK∗ to C. From this, CK∗ is a counital non-commutative non-cocommutative C ∗bialgebra. Furthermore, C∗-bialgebra automorphisms, a tensor product of repr...

Bonn States on the Cuntz Algebras and P-adic Random Walk States on the Cuntz Algebras and P-adic Random Walk States on the Cuntz Algebras and P -adic Random Walk

We study Markov measures and a p-adic random walk with the use of states on the Cuntz algebras Op. Via the GNS-construction, these come from families of representations of Op. We prove that these representations reflect self-similarity especially well. In this paper we consider a Cuntz-Krieger type algebra where the adjacency matrix depends on a parameter q (q = 1 is the case of Cuntz-Krieger)....

A tensor product of representations of Cuntz algebras

We introduce a nonsymmetric, associative tensor product among representations of Cuntz algebras by using embeddings. We show the decomposition formulae of tensor products for permutative representations explicitly We apply decomposition formulae to determine properties of endomorphisms.
