Liouville conformal field theory (LCFT hereafter), introduced by Polyakov in his 1981 seminal work "Quantum geometry of bosonic strings", can be seen as a random version of the theory of Riemann surfaces. A major issue in theoretical physics was to solve the theory, namely compute the correlation functions. In this direction, an intriguing formula for the three point correlations of LCFT was proposed in the middle of the 90's by Dorn-Otto and Zamolodchikov-Zamolodchikov, the celebrated DOZZ formula.

Recently, we gave a rigorous probabilistic construction of Polyakov's path integral formulation of LCFT using the Gaussian Free Field. In this talk, I will show that the three point correlation functions of the probabilistic construction indeed satisfy the DOZZ formula. This establishes an explicit link between probability theory (or statistical  physics) and the so-called conformal bootstrap approach of LCFT. Based on a series of joint works with David, Kupiainen and Rhodes.
