Research Abstract

I got many results on various classes of C^*-algebras related to noncommutative dynamical systems from the viewpoint of classification theory. As consequences of these results, I had succeeded in solving two long-standing problems, namely Dixmier's problem on the definition of UHF algebras and problems on semiprojectivity raised by Blackadar and others. I had also succeeded in getting the results on graph C^*-algebras and their generalizations relating classification theory directly.
