When is a Frobenius monoidal functor a Frobenius monoid?

Micah Blake McCurdyยท9 March 2011

We tenuously connect three results:

1) Jeff Egger has developed a construction of functor categories between star-autonomous categories which specialises to cover linearly-distributive categories in some cases.

2) Craig Pastro and Ross Street have shown that, for F a separable frobenius monoid in a braided monoidal category, there is a weak bialgebra structure on the tensor product of F with itself.

3) In my thesis, I show that every separable Frobenius monoidal functor gives rise to a weak-bialgebra in its codomain.

Modulo some technical wrinkles which we will discuss, it appears as though the Tannaka construction of 3) can be obtained as a composite of processes 1) and 2).
