Residually Finite Dimensional C*-algebras
A C*-algebra is called residually finite dimensional (RFD for brevity) if it has a separating family of finite dimensional representations. A C*-algebra A is said to be AF embeddable if there is an AF algebra B and a ∗-monomorphisms α : A→ B. In this note we discuss the question of AF embeddability of RFD algebras. Since a C*-subalgebra of a nuclear C*-algebra must be exact [Ki], the nonexact R...
متن کاملOperator Spaces and Residually Finite-dimensional C * -algebras
For every operator space X the C∗-algebra containing it in a universal way is residually finite-dimensional (that is, has a separating family of finitedimensional representations). In particular, the free C∗-algebra on any normed space so is. This is an extension of an earlier result by Goodearl and Menal, and our short proof is based on a criterion due to Exel and Loring.
متن کاملAn Endomorphism of a Finitely Generated Residually Finite Group
Let φ : G→ G be an endomorphism of a finitely generated residually finite group. R. Hirshon asked if there exists n such that the restriction of φ to φn(G) is injective. We give an example to show that this is not always the case.
متن کاملNon-linear residually finite groups
We prove that groups 〈a, b, t | tat = a, tbt = b〉 are not linear provided k, l 6∈ {−1, 1}. As a consequence we obtain the first example of a non-linear residually finite 1related group.
متن کاملRESIDUALLY FINITE RATIONALLY p GROUPS
In this article we develop the theory of residually finite rationally p (RFRp) groups, where p is a prime. We first prove a series of results about the structure of finitely generated RFRp groups (either for a single prime p, or for infinitely many primes), including torsion-freeness, a Tits alternative, and a restriction on the BNS invariant. Furthermore, we show that many groups which occur n...
