Description
Consider a finite modular tensor category A. In [DGGPR] the authors exhibit a 3-dimensional topological field theory Z_A: Bord_A -> Vect, which, in the case where A is semisimple, recovers the usual Reshetikhin-Turaev TQFT. In the present work we show that this extends naturally to a TQFT which takes values in the symmetric tensor category of linear cochains. This cochain valued theory furthermore respects (certain classes of) homotopies.
