59 p, 756.1 KB KMS states and continuous orbit equivalence for ultragraph shift spaces with sinks / Tasca, Felipe Augusto (Universidade Federal de Santa Catarina) ; Gonçalves, Daniel (Universidade Federal de Santa Catarina. Departamento de Matemática)
We extend ultragraph shift spaces and the realization of ultragraph C∗-algebras as partial crossed products to include ultragraphs with sinks (under a mild condition, called (RFUM2), which allows us to dismiss the use of filters) and we describe the associated transformation groupoid. [...]

51 p, 760.2 KB A bivariant theory for the Cuntz semigroup / Bosa Puigredon, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Tornetta, Gabriele (University of Glasgow. School of Mathematics and Statistics (UK)) ; Zacharias, Joachim (University of Glasgow. School of Mathematics and Statistics (UK))
We introduce a bivariant version of the Cuntz semigroup as equivalence classes of order zero maps generalizing the ordinary Cuntz semigroup. The theory has many features formally analogous to KK-theory including a composition product. [...]

160 p, 888.8 KB A new invariant for C*-algebras / Cantier, Laurent ; Antoine Riolobos, Ramon, dir. ; Perera Domènech, Francesc, dir. ; Universitat Autònoma de Barcelona. Departament de Matemàtiques
L'objectiu principal d'aquesta tesi és l'estudi d'un nou invariant per a C*-àlgebres, anomenat el semigrup Cu1. La classificació de C*-àlgebres ha guanyat molt terreny durant les últimes dècades. [...]
El objetivo principal de esta tesis es el estudio de un nuevo invariante para C*-álgebras, llamado el semigrupo Cu1. La clasificación de C*-álgebras ha ganado mucho terreno durante las últimas décadas. [...]
The main objective of this thesis is the study of a new invariant for C*-algebras, called the Cu1 semigroup. The classification of C*-algebras has gained a lot of ground during the last decades. For that matter, two main objects stand out: the original Elliott invariant, consisting of K-Theoretical data, together with traces, and a pairing between them, and the Cuntz semigroup. [...]
