Free products with amalgamation over central C*-subalgebras
Kristin Courtney, Tatiana Shulman
Let A and B be C*-algebras whose quotients are all RFD, and let C be a central C*-subalgebra in both A and B. We prove that the full amalgamated free product of A and B over C is t…
C*-stability of discrete groups
Søren Eilers, Tatiana Shulman, Adam P. W. Sørensen
A group may be considered -stable if almost representations of the group in a -algebra are always close to actual representations. We initiate a systematic study of which…
Elements of -algebras Attaining Their Norm in a Finite-Dimensional Representation
Kristin Courtney, Tatiana Shulman
We characterize the class of RFD -algebras as those containing a dense subset of elements that attain their norm under a finite-dimensional representation. We show further tha…
On algebras generated by inner derivations
Tatiana Shulman, Victor Shulman
We look for an effective description of the algebra D_{Lie}(X,B) of operators on a bimodule X over an algebra B, generated by inner derivations. It is shown that in some important…
