The completely bounded approximation property for extended Cuntz-Pimsner algebras Academic Article uri icon


  • 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 invariant Λ(·) for these algebras, the main result being that Λ(E(H) = Λ(B) when H is full over B. In particular, E(H) has the completely bounded approximation property if and only if the same is true for B. © 2005 University of Houston.
