On 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 کاملOn isometric embeddings of Hilbert’s cube into c
In our note, we prove the result that the Hilbert’s cube equipped with lp−metrics, p ≥ 1, cannot be isometrically embedded into c.
متن کاملProper Holomorphic Embeddings of Finitely and Infinitely Connected Subsets of C into C
We show that any finitely connected domain U ⊂ C can be properly embedded into C 2. For many sequences {p j } ⊂ U , U \ {p j } can also be properly embedded into C 2 .

متن کاملc-Frames and c-Bessel mappings
The theory of c-frames and c-Bessel mappings are the generalizationsof the theory of frames and Bessel sequences. In this paper, weobtain several equivalent conditions for dual of c-Bessel mappings.We show that for a c-Bessel mapping $f$, a retrievalformula with respect to a c-Bessel mapping $g$ is satisfied if andonly if $g$ is sum of the canonical dual of $f$ with a c-Besselmapping which wea...
