symmetric monoidal (∞,1)-category of spectra
The lift of the notion of Hopf bialgebra from associative algebras to tensor categories.
By the corresponding higher Tannaka duality, the 2-category of module categories over a Hopf monoidal category is a monoidal 2-category with duals.
Related to 4d TQFT as Hopf algebras are related to 3d TQFT.
Just as monoidal categories with fiber functor are the categories of modules of a Hopf algebra, so Hopf monoidal categories are supposed to be the categories of modules of a trialgebra.
