TL;DR
This paper compares proposed exact three-point functions in Liouville quantum field theory with a longstanding nonperturbative weak coupling expansion, finding exact agreement up to order O(g^{10}).
Contribution
It demonstrates the consistency between the exact proposals and the nonperturbative expansion in Liouville theory up to high order corrections.
Findings
Exact agreement with the weak coupling expansion up to O(g^{10})
Validation of the proposed three-point function in Liouville theory
Supports the reliability of the exact solution methods
Abstract
A comparison is made between proposals for the exact three point function in Liouville quantum field theory and the nonperturbative weak coupling expansion developed long ago by Braaten, Curtright, Ghandour, and Thorn. Exact agreement to the order calculated (i.e. up to and including corrections of order O(g^{10})) is found.
