Sphere and disk partition functions in Liouville and in matrix integrals

High Energy Physics - Theory 2022-08-10 v1

Abstract

We compute the sphere and disk partition functions in semiclassical Liouville and analogous quantities in double-scaled matrix integrals. The quantity sphere/disk^2 is unambiguous and we find a precise numerical match between the Liouville answer and the matrix integral answer. An application is to show that the sphere partition function in JT gravity is infinite.
