Functorial quantum field theory
The Reshetikhin-Turaev construction is the FQFT construction of a 3d TQFT from the data of a modular tensor category . It is something like the “square root” of the Turaev-Viro construction on .
In the case that is a category of positive energy representations of a loop group of a Lie group , then this algebraically defined QFT is thought to be the result of quantization of Chern-Simons theory over the group .
Relation to Chern-Simons theory
The RT-construction for group is expected to be the FQFT of -Chern-Simons theory, though a fully explicit proof of this via quantization is currently not in the literature.
See at quantization of Chern-Simons theory for more on this.
Relation to conformal field theory
The Fuchs-Runkel-Schweigert-construction builds from the RT-construction explicitly the rational 2-dimensional 2d CFT boundary theory (see at holographic principle).
