报告摘要:
Villadsen algebras of the first type were constructed in 1998 as examples of simple unital C*-algebras which have perforation in their ordered K_0 group. This class of C*-algebras lies outside the scope of the current classification theorem, as Villadsen algebras do not absorb the Jiang-Su algebra Z tensorially. We shall show that such algebras can be classified by the K_0 group together with the radius of comparison. Also, we shall show that such algebras are singly generated. These works are joint with Elliott, Niu and Ruzicka.
