چکیده

Let $\mathcal{A}= \{A_t \}_{t \in G}$ and $\mathcal{B}= \{B_t \}_{t\in be $C^*$-algebraic bundles over a finite group $G$. $C=\oplus_{t G}A_t$ $D=\oplus_{t\in G}B_t$. Also, let $A=A_e$ $B=B_e$, where $e$ is the unit element in We suppose that $C$ $D$ are unital $A$ $B$ have elements $D$, respectively. In this paper, we shall show if there an equivalence $\mathcal{A}-\mathcal{B}$-bundle $G$ with some properties, then inclusions of $C^*$-algebras $A \subset C$ $B D$ induced by $\mathcal{A}$ $\mathcal{B}$ strongly Morita equivalent. saturated $A' \cap C= \mathbf{C} 1$. equivalent, automorphism $f$ bundle $\mathcal{A}-\mathcal{B}^f $-bundle $\mathcal{B}^f$ $f$, which defined $\mathcal{B}^f = \{B_{f(t)} G}$. Furthermore, give application.

Topological Stable Rank of Inclusions of Unital C*-algebras

Let 1 ∈ A ⊂ B be an inclusion of C*-algebras of C*-index-finite type with depth 2. We try to compute topological stable rank of B (= tsr(B)) when A has topological stable rank one. We show that tsr(B) ≤ 2 when A is a tsr boundedly divisible algebra, in particular, A is a C*-minimal tensor product UHF ⊗ D with tsr(D) = 1. When G is a finite group and α is an action of G on UHF, we know that a cr...

Isomorphisms in unital $C^*$-algebras

It is shown that every  almost linear bijection $h : Arightarrow B$ of a unital $C^*$-algebra $A$ onto a unital$C^*$-algebra $B$ is a $C^*$-algebra isomorphism when $h(3^n u y) = h(3^n u) h(y)$ for allunitaries  $u in A$, all $y in A$, and all $nin mathbb Z$, andthat almost linear continuous bijection $h : A rightarrow B$ of aunital $C^*$-algebra $A$ of real rank zero onto a unital$C^*$-algebra...

On Morita Equivalence of Group Actions on Locally C-algebras

In this paper, we prove that two continuous inverse limit actions α and β of a locally compact group G on the locally C-algebras A and B are strongly Morita equivalent if and only if there is a locally C-algebra C such that A and B appear as two complementary full corners of C and there is a continuous action γ of G on C which leaves A and B invariant such that γ|A = α and γ|B = β. This general...

Property (T) for non-unital C ∗-algebras ∗

Inspired by the recent work of Bekka, we study two reasonable analogues of property (T ) for not necessarily unital C∗-algebras. The stronger one of the two is called “property (T )” and the weaker one is called “property (Te)”. It is shown that all non-unital C*-algebras do not have property (T ) (neither do their unitalizations). Moreover, all non-unital σ-unital C*-algebras do not have prope...

Non-Commutative Vector Bundles for Non-Unital Algebras

We revisit the characterisation of modules over non-unital C∗-algebras analogous to modules of sections of vector bundles. A fullness condition on the associated multiplier module characterises a class of modules which closely mirror the commutative case. We also investigate the multiplier-module construction in the context of bi-Hilbertian bimodules, particularly those of finite numerical inde...
