In this paper, we show that, more generally, 3‐categories with one object and 1‐morphisms given by elements of a group G$G$ correspond to G$G$ ‐crossed braided categories, certain mathematical structures which have emerged as important invariants of low‐dimensional quantum field theories. More precisely, we show that the 4‐category of 3‐categories C$\mathcal {C}$ equipped with a 3‐functor BG→C$\mathrm{B}G \rightarrow \mathcal {C}$ which is essentially surjective on objects and 1‐morphisms is equivalent to the 2‐category of G$G$ ‐crossed braided categories. This provides a uniform approach to various constructions of G$G$ ‐crossed braided categories.}, journal={JOURNAL OF THE LONDON MATHEMATICAL SOCIETY-SECOND SERIES}, author={Jones, Corey and Penneys, David and Reutter, David}, year={2022}, month={Nov} } @article{bischoff_jones_2022, title={Computing fusion rules for spherical G-extensions of fusion categories}, volume={28}, ISSN={["1420-9020"]}, DOI={10.1007/s00029-021-00725-3}, abstractNote={A G-extension of a fusion category $${\mathcal {C}}$$ yields a categorical action of G on the center $$Z({{\mathcal {C}}})$$ .

The class $[\omega]\in H^{3}(G, \text{U}(1))$ is called the anomaly of the action. We show for every $n\ge 2$ and every finite group $G$, every anomaly can be realized on the stabilization of a commutative C*-algebra $C(M)\otimes \mathcal{K}$ for some closed connected $n$-manifold $M$. We also show that although there are no anomalous symmetries of Roe C*-algebras of coarse spaces, for every finite group $G$, every anomaly can be realized on the Roe corona $C^{*}(X)/\mathcal{K}$ of some bounded geometry metric space $X$ with property $A$.}, number={1}, journal={COMMUNICATIONS IN MATHEMATICAL PHYSICS}, author={Jones, Corey}, year={2021}, month={Nov}, pages={385–417} } @article{jones_2021, title={Triangle presentations and tilting modules for SL2k+1}, volume={5}, ISSN={["2415-6310"]}, DOI={10.4171/JCA/50}, number={1}, journal={JOURNAL OF COMBINATORIAL ALGEBRA}, author={Jones, Corey}, year={2021}, pages={59–92} }
