Idea

The Turaev-Viro model, or more precisely Turaev-Viro-Barrett-Westbury 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.

Properties

As an extended TQFT

The Turaev-Viro model has been constructed as a 3-2-1 extended TQFT in (Kirillov-Balsam 10, Balsam 10a, Balsam 10b).

Related but different is the construction of fully extended 3d TQFT from fusion categories via the cobordism theorem, see at fusion category – Relation to extended 3d TQFT for more on this.
