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…
Representations of Group Algebras in Spaces of Completely Bounded Maps
Roger R. Smith, Nico Spronk
Let G be a locally compact group, M(G) denote its measure algebra and L^1(G) denote its group algebra. Also, let pi:G->U(H) be a strongly continuous unitary representation, and let…
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…
Crossed products and entropy of automorphisms
Ciprian Pop, Roger R. Smith
Let A be an exact C^*-algebra, let G be a locally compact group, and let (A,G,α) be a C*-dynamical system. Each automorphism α_g induces a spatial automorphism Ad_{\lamba_g} on the…
One-Sided Projections on C*-algebras
David P. Blecher, Roger R. Smith, Vrej Zarikian
In [BEZ] the notion of a complete one-sided M-ideal for an operator space X was introduced as a generalization of Alfsen and Effros' notion of an M-ideal for a Banach space [AE72].…
Unitary perturbations of masas in type factors
Allan M. Sinclair, Roger R. Smith
We investigate maximal abelian subalgebras (masas) in separably acting type factors. We use the notion of distance between masas which we introduced in an earlier paper in t…
