"Conformal Bootstrap in Liouville Theory"
A. Polyakov introduced Liouville Conformal Field theory (LCFT) in 1981 as a building block of non-critical string theory. Ever since, the work of Polyakov has echoed in various branches of physics and mathematics. In the context of 2D quantum gravity models LCFT describes the scaling limit of spin systems on random lattices and through the Alday-Gaiotto-Tachikava correspondence LCFT is related to certain 4D Yang-Mills theories. Through the work of Dorn,Otto, Zamolodchikov and Zamolodchikov and Teschner LCFT is believed to be to a certain extent integrable.
I will review a probabilistic construction of LCFT developed together with David, Rhodes and Vargas and recent proofs concerning the integrability of LCFT:
-The proof in a joint work with Rhodes and Vargas of the DOZZ formula (Annals of Mathematics, 81-166,191 (2020) -The proof in a joint work with Guillarmou, Rhodes and Vargas of the bootstrap conjecture for LCFT (arXiv:2005.11530).
