© Copyright by THETA, 2016. We give a complete classification of the ideals of the core of the C*-algebras associated with self-similar maps under a certain condition. Any ideal is completely determined by the intersection with the coefficient alg...

Let R be a rational function. The iterations (Rn)nof R gives a complex dynamical system on the Riemann sphere. We associate a C*-algebra and study a relation between the C*-algebra and the original complex dynamical system. In this short note, we ...

We study Kubo-Martin-Schwinger (KMS) states on finite-graph C*-algebras with sinks and sources. We compare finite-graph C*-algebras with C*-algebras associated with complex dynamical systems of rational functions. We show that if the inverse tempe...

Let p(z,w) be a polynomial in two variables. We call the solution of the algebraic equation p(z,w) = 0 an algebraic correspondence. We regard it as the graph of the multivalued function z → w defined implicitly by p(z,w) = 0. Algebraic corresponde...

We show that any countable subgroup of the multiplicative group R+×of positive real numbers can be realized as the fundamental group F(A) of a separable simple unital C*-algebra A with unique trace. Furthermore for any fixed countable subgroup G o...
