The completely bounded approximation property for extended Cuntz-Pimsner algebras
Kenneth J. Dykema, Roger R. Smith
The extended Cuntz-Pimsner algebra E(H), introduced by Pimsner, is constructed from a Hilbert B,B-bimodule H over a C*-algebra B. In this paper we investigate the Haagerup invarian…

Perturbations of Subalgebras of Type Factors
Sorin Popa, Allan Sinclair, Roger Smith
We consider two von Neumann subalgebras $\cl B_0$ and $\cl B$ of a type factor $\cl N$. For a map on $\cl N$, we define \[\|ϕ\|_{\infty,2}=\sup\{\|ϕ(x)\|_2\colon…
