Research Abstract |
We classified KMS states on C^*-algebras constructed from the dynamical system on Riemannian sphere by rational functions and self-similar maps. Especially, we have made a complete classification for rational function cases. We constructed C^*-algebras using Hilbert C^*-bimodules for algebraic correspondences, which are generalization of rational functions, and have got sufficient conditions for simplicity and pure infiniteness of such C^*-algebras. We constructed concrete examples of countable infinite basis for Hilbert C^*-modules constructed from dynamical systems which have branch points, for example, rational functions and self-similar maps.
