Abstract
Lecture notes prepared for the Les Houches school "Quantum Geometry: Mathematical Methods for Gravity, Gauge Theories and Non-Perturbative Physics" that took place during the summer 2024. We cover the techniques to perform the exact gravitational path integral of two-dimensional dilaton-gravity, and supergravity, over spacetimes with arbitrary topology, with an application to black holes. We discuss the connection with random matrix models and moduli spaces of hyperbolic surfaces briefly, since those concepts were covered in other lectures of the school.

Strengths
Weaknesses
Report
I have not reproduced detailed calculations, however to the extent that I have gone through the technical arguments they are sound and in line with the cited literature.
These lecture notes easily meet the criteria of SciPost Physics Lecture Notes.
Requested changes
I found one (very minor) typo: above equation (5.22) "read of..." should be "read off..."
Recommendation
Publish (surpasses expectations and criteria for this Journal; among top 10%)
