    Object:For irreversible discrete dynamical systems with branched points such as rational functions on Riemanian sphere and self-similar maps, we construct C*-algebras using Hilbert C*-bimodule and investigate the original dynamical systems using the analysis of the algebraic stgrucute of the associated C*-algebras. Recently, we mainly study the core, the fixed point algebra under the gaugeg action, of the associated C*-alagebras.
