Twisted Topological Graph Algebras Are Twisted Groupoid C*-algebras
, 2017 The second author showed how Katsura's construction of the C*-algebra of a topological graph E may be twisted by a Hermitian line bundle L over the edge space E.

Journal of Applied Crystallography, Volume 58, Issue 3, Page 768-788, June 2025.Novel linearization routines within the parameter space concept (PSC) provide an alternative approach to determine one‐dimensionally projected crystal structures from a few diffraction intensities of standard Bragg reflections, represented by piecewise analytic hyper‐surfaces, without the use of Fourier inversion.

Cuntz-Krieger algebras associated with Hilbert $C^*$-quad modules of commuting matrices [PDF]
, 2012 Let ${\cal O}_{{\cal H}^{A,B}_\kappa}$ be the $C^*$-algebra associated with the Hilbert $C^*$-quad module arising from commuting matrices $A,B$ with entries in $\{0,1\}$.

Unitary equivalence of automorphisms of separable C*-algebras
, 2013 We prove that the automorphisms of any separable C*-algebra that does not have continuous trace are not classifiable by countable structures up to unitary equivalence.

Some metric characterizations of commutativity in C*-algebras [PDF]
Surveys in Mathematics and its ApplicationsWe study Le Page's theorem in the context of C*-algebras and obtain several characterizations of commutativity and centrality implied by identities or inequalities satisfied by the norm.

The K-theory ranks for crossed products of C*-algebras by the group of integers
Cubo, 2019 We study the K-theory ranks for crossed products of C∗-algebras by the group of integers. As an application, we obtain certain estimates for the K-theory ranks of the group C∗-algebras of torsion free, finitely generated, nilpotent or solvable discrete ...

MATHEMATICA SCANDINAVICA, 2010 We investigate relations on elements in $C^{*}$-algebras, including $*$-polynomial relations, order relations and all relations that correspond to universal $C^{*}$-algebras. We call these $C^{*}$-relations and define them axiomatically. Within these are the compact $C^{*}$-relations, which are those that determine universal $C^{*}$-algebras, and we ...

The in crystallo optical spectroscopy toolbox
Journal of Applied Crystallography, Volume 58, Issue 3, Page 1068-1078, June 2025.The rise of time‐resolved macromolecular crystallography has been accompanied by renewed interest in companion biophysical characterization methods applicable to molecules both in solution and in crystallo. Here, we present a workflow and a graphical interface for analysing spectroscopic data collected on macromolecular crystals.Over the past ten years,
