Negative screenings in Liouville theory
We demonstrate how negative powers of screenings arise as a nonperturbative effect within the operator approach to Liouville theory. This explains the origin of the corresponding poles in the exact Liouville three point function proposed by Dorn/Otto and (\hbox{Zamolodchikov })^2 (DOZZ) and leads to...
