  2. 1. Amenable-like properties of étale groupoids

    Author : Gabriel Favre; Sven Raum; Nadia Larsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Etale groupoids; Representation theory; amenability; inverse semigroups; C*-algebra; matematik; Mathematics;

    Abstract : This thesis consists of three papers related to analytic and representation theoretic properties of étale groupoids.In the first paper, we characterize algebraically the type I and CCR property for ample groupoids and their non-commutative duals: Boolean inverse semigroups. Our results use and generalize Thoma’s work on discrete groups. READ MORE

  4. 2. The type I and CCR properties for groupoids and inverse semigroups

    Author : Gabriel Favre; Sven Raum; Fernando Llédo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Representations; groupoids; type I; Operator algebra; unitary representation;

    Abstract : This licentiate thesis consists of one paper about unitary representationtheory of ample groupoids and semigroups together with generalizationsto étale and non-Hausdorff groupoids. In the paper we study algebraically the type I and CCR properties forample Hausdorff groupoids. READ MORE
