The structure of doubly non-commuting isometries

Marcel de Jeu, Paulo R. Pinto

Suppose that $n \geq 1$ and that, for all $i$ and $j$ with $1 \leq i, j \leq n$ and $i \neq = j$ , $z_{ij} \in T$ are given such that $z_{j i} = z_{ij}$ for all $i \neq = j$ .…

The closure of ideals of $ℓ^{1} (Σ)$ in its enveloping $C^{*}$ -algebra

Marcel de Jeu, Jun Tomiyama

If $X$ is a compact Hausdorff space and $σ$ is a homeomorphism of $X$ , then an involutive Banach algebra $ℓ^{1} (Σ)$ of crossed product type is naturally associated with the topolo…

Nonsimplicity of certain universal $C^{*}$ -algebras

Marcel de Jeu, Rachid El Harti, Paulo R. Pinto

Given $n \geq 2$ , $z_{ij} \in T$ such that $z_{ij} = z_{j i}$ for $1 \leq i, j \leq n$ and $z_{ii} = 1$ for $1 \leq i \leq n$ , and integers $p_{1}, ..., p_{n} \geq 1$ , we show that…

Algebraically irreducible representations and structure space of the Banach algebra associated with a topological dynamical system

Marcel de Jeu, Jun Tomiyama

If $X$ is a compact Hausdorff space and $σ$ is a homeomorphism of $X$ , then a Banach algebra $ℓ^{1} (Σ)$ of crossed product type is naturally associated with this topological dynam…

A characterisation of C*-algebras through positivity of functionals

Marcel de Jeu, Jun Tomiyama

We show that a unital involutive Banach algebra, with identity of norm one and continuous involution, is a C*-algebra, with the given involution and norm, if every continuous linea…

Maximal abelian subalgebras and projections in two Banach algebras associated with a topological dynamical system

Marcel de Jeu, Jun Tomiyama

If $Σ = (X, σ)$ is a topological dynamical system, where $X$ is a compact Hausdorff space and $σ$ is a homeomorphism of $X$ , then a crossed product Banach $\sp{*}$-algebra $ℓ^{1} (Σ)$ …

On the Banach $*$ -algebra crossed product associated with a topological dynamical system

Marcel de Jeu, Christian Svensson, Jun Tomiyama

Given a topological dynamical system $Σ = (X, σ)$ , where $X$ is a compact Hausdorff space and $σ$ a homeomorphism of $X$ , we introduce the associated Banach $^{*}$ -algebra crossed pro…

Dynamical systems associated with crossed products

Christian Svensson, Sergei Silvestrov, Marcel de Jeu

In this paper, we consider both algebraic crossed products of commutative complex algebras A with the integers under an automorphism of A, and Banach algebra crossed products of co…
