SUMMARY
The discussion focuses on calculating the on-shell action for an AdS Schwarzschild black hole. The user attempts to apply a Gibbons-Hawking boundary term, similar to that used for flat Minkowski spacetime, but encounters issues with obtaining a finite result as the limit approaches infinity. The need for an appropriate counter-term to achieve a finite answer is emphasized, indicating that the standard approach may not suffice for this specific black hole geometry.
