Outline of Final Research Achievements

In this research, we got not only various results on C*-algebras over finite spaces as expected, but also wide results on classification theory of C*-algebras. The results on C*-algebras over finite spaces include the one on K-theoretical invariants of Cuntz-Krieger algebras with the application to the conjecture of characterization of graph algebras, the complete solution to realization problem of K-theoretical invariants of non-simple graph algebras, and the result of determining which AF-algebras arise as non-simple graph algebras. The results on classification theory of C*-algebras include the ones on non-separable C*-algebras and on C*-algebras associated with discrete groups.
