The functor Max of Mulvey assigns to each unital C*-algebra A the unital involutive quantale Max A of closed linear subspaces of A, and it has been remarked that it classifies unital C*-algebras up to ∗-isomorphism. In this paper we provide a proof of this and of the stronger fact that for every isomorphism u : Max A → Max B of unital involutive quantales there is a ∗-isomorphism b : A → B such that Max b u coincides with u when restricted to the left-sided elements of Max A. But we also show… 

Groupoid sheaves as Hilbert modules

We provide a new characterization of the notion of sheaf on an ´ groupoid G, in terms of a particular kind of Hilbert module on the quantale O(G) of the groupoid. All the theory is developed in the

Prime Elements of Non-integral Quantales and their Applications

Every spatial semiunital quantale can be identified with a many-valued sober space and this result is applied to the topologization of spectra of non-commutative C∗-algebras.

Prime Elements of Non-integral Quantales and their Applications

The quantisation of the Boolean algebra 2 is given by the semi-integral regularization of the quantale of all join preserving self-maps of the chain of three elements. On this basis prime elements of

On the Structure of Closed Right Ideals of a C*-Algebra

The lattice of closed right ideals is an important invariant of a C*-algebra and naturally generalizes the spectrum of a commutative C*-algebra. As the C*-algebra is a union of its commutative

Quantales of open groupoids

It is well known that inverse semigroups are closely related to \'etale groupoids. In particular, it has recently been shown that there is a (non-functorial) equivalence between localic \'etale

On Quantales and Spectra of C*-Algebras

Although Max is not an equivalence of categories, therefore not providing a direct generalization of Gelfand duality to the noncommutative case, it is a faithful complete invariant of unital C*-algebras.

Simple Involutive Quantales

Abstract Involutive quantales were introduced in [7] as complete lattices equipped with a multiplication and an involution. Such structures are well known from the calculus of relations: the set R

A Noncommutative Theory of Penrose Tilings

Considering quantales as generalised noncommutative spaces, we address as an example a quantale Pen based on the Penrose tilings of the plane. We study in general the representations of involutive
