About the QWEP conjecture
Narutaka Ozawa
This is a detailed survey on the QWEP conjecture and Connes' embedding problem. Most of contents are taken from Kirchberg's paper [Invent. Math. 112 (1993)].
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…
Homogeneity of the pure state space of a separable C*-algebra
A. Kishimoto, N. Ozawa, S. Sakai
We prove that the pure state space is homogeneous under the action of the automorphism group (or the subgroup of asymptotically inner automorphisms) for all the separable simple C*…
An Application of Expanders to
Narutaka Ozawa
With the help of Kirchberg's and Selberg's theorems, we prove that the minimal tensor product of with itself does not have the WEP (weak expectation property) of Lance.
