• A leisurely stroll through the theory of adjunctions

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Member Seminar Speaker: Lorenzo Riva, Harvard CMSA Title: A leisurely stroll through the theory of adjunctions Abstract: Adjoint functors (and, more generally, adjunctions in a 2-category) are ubiquitous in algebra and topology. In this talk I will give an overview of the basics of adjunctions, with the ultimate goal being understanding the statement of the […]

  • Constructing oriented TQFTs from twisted pivotal tensor categories

    CMSA Room G10 CMSA, 20 Garden Street, Cambridge, MA, United States

    Geometry and Quantum Theory Seminar Speaker: William Stewart Title: Constructing oriented TQFTs from twisted pivotal tensor categories Abstract: The cobordism hypothesis classifies n-dimensional oriented TQFTs in terms of SO(n) homotopy fixed point data. An SO(2) homotopy fixed point structure on a finite tensor category gives rise to a twisted pivotal structure (a more general notion […]
