| Outline of Final Research Achievements |
In this research, we associate C*-algebras with complex dynamical systems of iterations of rational functions R using Hilbert bimodule, and we have found interesting relations between operator algebras and complex dynamical systems. We can recover some properties of complex dynamical systems of R from the associated C*-algebras with the gauge action. We explain the structure of the singularity of branched points in terms of K-theory and KMS states for gauge actions. We determine the extreme points of the traces on the cores of the C*-algebras associated with self-similar maps. We find their ideal structure. We showed that the dimension group of the tent map is the free abelian infinite group and the shift on it.
