Villadsen algebras are singly generated

Chun Guang Li, Zhuang Niu, Vincent M. Ruzicka

We show that Villadsen algebras, which are not Z-stable, are singly generated. More generally, we show that any simple unital AH algebra with diagonal maps is singly generated.

$C^{*}$ exponential length of commutators unitaries in $A H$ algebras

Chun Guang Li, Liangqing Li, Iván Velázquez Ruiz

For each unital $C^{*}$ -algebra $A$ , we denote $ce l_{C U} (A) = sup {ce l (u) : u \in C U (A)}$ , where $ce l (u)$ is the exponential length of $u$ and $C U (A)$ is the closure of the commutator s…
