If you have a question about this talk, please contact nobody. TGAW02 - C*-algebras: classification and dynamical constructions C-categories have a rich history in the study of C-algebras, going back to work of Rieffel in the 1970s. Recent work of Ferrer provides a framework for C-tricategories, a higher category theoretic analogue of a C-category. Given an object $C$ of a higher category, one may compute the group of automorphisms of $C$ up to (higher) equivalence. In the C-tricategory $\normalfont\mathbf{CHaus}$, we construct the higher automorphism group of a compact Hausdorff space $T$ as an extension of the homeomorphism group of $T$ by its third cohomology group. This work is joint with Giovanni Ferrer. This talk is part of the Isaac Newton Institute Seminar Series series. This talk is included in these lists:
