Invertible fusion categories

Abstract A tensor category $$\mathcal C$$ C over a field $$\mathbb K$$ K is said to be invertible if there’s a tensor category $$\mathcal D$$ D such that $$\mathcal C \boxtimes \mathcal D$$ C ⊠ D is Morita equivalent to $$\textrm{Vec}_{\mathbb K}$$ Vec K . When $$\mathbb K$$ K is...
