Exactness of Universal Free Products of Finite Dimensional C-algebras with Amalgamation
نویسنده
چکیده
Recall that for C-algebras A and B there are many possible norms on A ⊗ B for which the completion is a C-algebra. In particular there are two standard completions A ⊗min B and A⊗max B corresponding to the ‘smallest’ and ‘largest’ possible tensor norms. We say that A is nuclear if these two tensor products correspond for all C-algebras B. We say that a C-algebra A is exact if given any short exact sequence of C-algebras

Product preservation and stable units for reflections into idempotent subvarieties
We give a necessary and sufficient condition for the preservation of finite products by a reflection of a variety of universal algebras into an idempotent subvariety. It is also shown that simple and semi-left-exact reflections into subvarieties of universal algebras are the same. It then follows that a reflection of a variety of universal algebras into an idempotent subvariety has stable units...
متن کاملExactness of Cuntz–pimsner C–algebras
Let H be a full Hilbert bimodule over a C-algebra A. We show that the Cuntz–Pimsner algebra associated to H is exact if and only if A is exact. Using this result, we give alternative proofs for exactness of reduced amalgemated free products of exact C– algebras. In the case that A is a finite–dimensional C–algebra, we also show that the Brown–Voiculescu topological entropy of Bogljubov automorp...
متن کاملOn Embeddings of Full Amalgamated Free Product C∗–algebras
An embedding question for full (i.e. universal) amalgamated free products of C∗–algebras is raised, and solved in part. This is used to give a necessary and sufficient condition for the full amalgamated free product of finite dimensional C∗–algebras to be residually finite dimensional.
متن کاملKhintchine type inequalities for reduced free products and Applications
We prove Khintchine type inequalities for words of a fixed length in a reduced free product of C∗-algebras (or von Neumann algebras). These inequalities imply that the natural projection from a reduced free product onto the subspace generated by the words of a fixed length d is completely bounded with norm depending linearly on d. We then apply these results to various approximation properties ...
متن کاملALGEBRAS WITH CYCLE-FINITE STRONGLY SIMPLY CONNECTED GALOIS COVERINGS
Let $A$ be a nite dimensional $k-$algebra and $R$ be a locally bounded category such that $R rightarrow R/G = A$ is a Galois covering dened by the action of a torsion-free group of automorphisms of $R$. Following [30], we provide criteria on the convex subcategories of a strongly simply connected category R in order to be a cycle- nite category and describe the module category of $A$. We p...
