Correlation functions in 2D string theory

P. Di Francesco, D. Kutasov

Research output: Contribution to journalArticlepeer-review


We calculate spherical N point correlation functions in string theories with c≤1. The amplitudes are given by two dimensional integrals, which we compute in their domain of convergence in momentum space. Outside of this domain, the amplitudes are non-analytic due to the existence of the Liouville interaction.
