| Research Abstract |
Our interst of this research is the study of non-commutatibity of topological spaces. We mainly treat operator algebras and regards them as objects of non-commutative topological spaces. C^*-algebras constructed by an inductive system or a C^*-dynamical system arestudied by many researchers and we can also get some results about them (works of H. Matui and K. Kodaka). These topics are related to K-tneory of C^*-algebras and the dimension theory of C^*-algebras. The work of Nagisa-O-P and Nagisa-K are related to them. To consider more complicated objects, Nagisa and Itoh gather result of operator spaces and study the relation of Schur multipliers and the Haagerup tensor product as its applications. Concerning this object, we can get interesting result.
