Free products of exact groups
Ken Dykema
It has recently been proved that the class of unital exact C*-algebras is closed under taking reduced amalgamated free products. In particular, this implied that the class of exact…
Topological entropy of some automorphisms of reduced amalgamated free product C*-algebras
Ken Dykema
Certain classes of automorphisms of recued amalgamated free products of C*-algebras are shown to have Brown-Voiculescu topological entropy zero. Also, for automorphisms of exact C*…
Projections in free product C*-algebras, II
Ken Dykema, Mikael Rordam
Let (A,phi) be the reduced free product of infinitely many pairs (A_i,phi_i) of C*-algebras with faithful states. Assume that the A_i are not too small, in a specific sense. It is…
Purely infinite, simple C*-algebras arising from free product constructions, III
Marie Choda, Ken Dykema
In the reduced free product of C*-algebras (A,phi)=(A_1,phi_1)*(A_2,phi_2), A is shown to be purely infinite and simple under the hypothesis that A_1 is the crossed product of a C*…
Purely infinite, simple C*-algebras arising from free product constructions, II
Ken Dykema
Certain reduced free products of C*-algebras, (A,phi)=(A_1,phi_1)*(A_2,ϕ_2), taken with respect to faithful states, at least one of which is not a trace, are shown to be purely inf…
Exactness of Cuntz-Pimsner C*-algebras
Ken Dykema, Dimitri Shlyakhtenko
Let H be a full Hilbert bimodule over a C*-algebra A. We show that the Cuntz-Pimsner C*-algebra associated to H is exact if and only if A is exact. Using this result, we give alter…
