In the setting of product systems over group-embeddable monoids, we consider nuclearity of the associated Toeplitz C*-algebra in relation to nuclearity of the coefficient algebra. Our work goes beyond the known cases of single correspondences and com

Given a C$^*$-algebra $A$ with an almost periodic time evolution $\sigma$, we define a new C$^*$-algebra $A_c$, which we call the crystal of $(A,\sigma)$, that represents the zero temperature limit of $(A, \sigma)$. We prove that there is a one-to-on

We introduce the notion of relative topological principality for a family $\{H_\alpha\}$ of open subgroupoids of a Hausdorff \'etale groupoid $G$. The C*-algebras $C^*_r(H_\alpha)$ of the groupoids $H_\alpha$ embed in $ C^*_r(G)$ and we show that if

Debido a su durabilidad, versatilidad y bajo coste, los productos plásticos resultan fundamentales en la sociedad actual; sin embargo, estas mismas propiedades, responsables de su gran popularidad, también convierten a estos materiales en una amena

The present study aimed to analyse the factor structure of the Melbourne Decision Making Questionnaire (DMQ-II), and to examine the relationships between the factors identified and Self-confidence, in order to conceptualize the decision-making proces

We use a groupoid model for the spin algebra to introduce boundary conditions on quantum spin systems via a Poisson point process representation. We can describe KMS states of quantum systems by means of a set of equations resembling the standard DLR

We generalise recent results of Afsar, Larsen and Neshveyev for product systems over quasi-lattice orders by showing that the equilibrium states of quasi-free dynamics on the Nica-Toeplitz $C^*$-algebras of product systems over right LCM monoids must

This paper summarises the results of the first analytical investigation of the soil chemistry of Asturian Megalithism, an approach which is essential, due to the scarcity of materials conserved in the burial areas. The combination of three analytical
