The Turaev-Viro model is a 3d TQFT construction induced from a spherical category/fusion category 𝒞\mathcal{C}.

If 𝒞\mathcal{C} is moreover a modular tensor category then there exists also the Reshetikhin-Turaev construction 3d TQFT. In this case the Turaev-Viro model is something like the “norm square” of the Reshetikhin-Turaev construction on 𝒞\mathcal{C}.

For GG a finite group and 𝒞=Vect G\mathcal{C} = Vect_G the category of GG-graded vector spaces the Turaev-Viro model describes the GG-Dijkgraaf-Witten theory, also the Levin-Wen model.

See for instance the introduction of (Kirillov-Balsam 10) for a review.


As a boundary of the Yetter model

The Turaev-Viro model is a boundary field theory of the 4d TQFT Yetter model (Barrett&Garci-Islas&Martins 04, theorem 2) Related discussion is in Freed4-3-2 8-7-6”.
