When the gravity path integral describes a statistical average
Gabriele Di Ubaldo, Luca V. Iliesiu, Henry W. Lin +1
We find the necessary and sufficient conditions for the gravitational path integral (GPI) to admit an interpretation in terms of (i) an inner product in the Hilbert space of open/c…

Positivity of the gravitational path integral implies the axionic weak gravity conjecture
Gabriele Di Ubaldo, Luca V. Iliesiu, Henry W. Lin +1
The gravitational path integral can compute inner products between different states of open and closed universes. To have a well-defined Hilbert space, these inner products should…
