Description
In this talk, I will discuss on-shell actions for type IIB supergravity and 11D M-Theory based on my recent papers (JHEP 06 (2026) 271 and 260X.XXXXX). In these works, we have consistently incorporated suitable topological terms that can be evaluated for a
large number of backgrounds. We also show that the on-shell actions for the original 10D and 11D supergravities obtained in our papers agree with the low-d wanted results. This consistency in the matching is important from the AdS/CFT point of view, since the free energy of boundary conformal field theory should match with the Euclidean
on-shell action of the effective supergravity. Our results thus place direct holographic comparisons within the ten-dimensional Type IIB and 11D M-theory framework on firmer ground. I will end my talk with some discussion.
