Drinfeld-Sokolov reduction of 2d BF theory and the Schwarzian theory (JDonald Youmans, Bern)

30.11.2021 15:30 – 16:30

In this talk we report on the holographic correspondence between 2d BF theory on the (punctured) disk with gauge group PSL(2,R) and the Schwarzian theory on the boundary. We realize the duality in terms of a Drinfeld-Sokolov reduction which is equivalent to enforcing a first class constraint. The constrained path integral localizes over (exceptional) Virasoro coadjoint orbits and can be computed by a formal Duistermaat-Heckman integration.

The talk is based on joint work with F. Valach.
