    BRAIDED QUANTUM SYMMETRIES OF GRAPH C*-ALGEBRAS

    In this talk, we will explain the existence of a universal braided compact quantum group acting on a graph C*-algebra in the twisted monoidal category of C*-algebras equipped with an action of the circle group. Along the way, we shall also present a braided version of the free unitary quantum gro...

    INFINITE-SUM RELATIONS IN C*-ALGEBRAS

    We build a universal C*-algebra using the strong operator topology to describe certain relations. In particular, this allows us to use infinite-sum relations. We show that these algebras have indeed a universal property, and then prove that the Exel-Laca algebras can be defined by consider...

    NONCOMMUTATIVE GEOMETRY AND DUALITY OF ORIENTIFOLD FIELD THEORIES

    An important phenomenon in modern physics is that, often, very different field theories give rise to identical physical predictions. This is what physicists usually call “duality”, though it does not always agree with the mathematical meaning of the term. In string theories, important in...

    CYCLIC HOMOLOGY, COEFFICIENTS, AND LIMITS

    Classically, coefficients for Hopf-cyclic homology were defined as objects that are both a module and a comodule with a compatibility between the two structures. This definition has been generalized to different settings with various levels of success. We will look at two cases where a limit-focused...
