On the Definition of C*-algebras
It is shown that conditions \Vert x y\Vert ≤ \Vert x\Vert \Vert y\Vert and \Vert x^*\Vert= \Vert x\Vert follow from the other axioms for

A method for constructing idempotents in a unital algebra
A method is proposed for constructing idempotents in a unital algebra 𝒜 using n arbitrary idempotents P1,...,Pn from this algebra. The properties of the resulting idempotents P = P(P1,...,Pn) are investigated; for n = 2 and n = 3, explicit forms of the ...

On Gradings of the Operator Algebra Generated by Mapping and Multipliers [PDF]
The operator algebra generated by mapping on a countable set and multipliers is considered. The defined mapping induces a family of partial isometries satisfying some relations.

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.

C∗-algebraic Gauss-Lucas Theorem and C∗-algebraic Sendov’s Conjecture
Building on a foundational result established by Robertson [Proc. Edinburgh Math. Soc., 1976], we develop a framework for differentiation of maps defined on specific classes of unital commutative C∗-algebras.

In this work we characterise the C*-algebras A generated by projections with the property that every pair of projections in A has positive angle, as certain extensions of abelian algebras by algebras of compact operators. We show that this property is equivalent to a lattice theoretic property of projections and also to the property that the set of ...

The in crystallo optical spectroscopy toolbox
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,

Relatively hyperbolic groups are C*-simple
We characterize relatively hyperbolic groups whose reduced C*-algebra is simple as those, which have no non-trivial finite normal ...
