There is no separable universal II_1-factor

Narutaka Ozawa

Gromov constructed uncountably many pairwise non-isomorphic discrete groups with Kazhdan's property (T). We will show that no separable II_1-factor can contain all these groups in…

On ${\OL}_{\infty}$ structure of nuclear -algebras

M. Junge, N. Ozawa, Z. J. Ruan

We study the local operator space structure of nuclear -algebras. It is shown that a -algebra is nuclear if and only if it is an $\OL_{\infty, \la}$ space for some (and a…

Homotopy invariance of AF-embeddability

Narutaka Ozawa

We prove that AF-embeddability is a homotopy invariant in the class of separable exact -algebras. This work was inspired by Spielberg's work on homotopy invariance of AF-embed…
